Alaska Airlines — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the alaska-airlines-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install alaska-airlines --cli-only
   

2. Verify: alaska-airlines-pp-cli --version
3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer):

go install github.com/mvanhorn/printing-press-library/library/travel/alaska-airlines/cmd/alaska-airlines-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

When to Use This CLI

Pick this CLI when an agent needs to search Alaska flights or check Atmos Rewards data programmatically with cached airport lookup and trimmed JSON output. Don't pick it for booking automation; the final pay POST is not replayable from a static binary and is not attempted.

Known Gaps

These capabilities were scoped in the manuscript for this CLI but were not implemented in this generation. They are not currently available; planning around them will fail with "unknown command" or "unknown flag" errors. Use the listed real command instead where applicable:

• book prepare (pre-checkout deeplink builder) - not implemented
• flights search --want-seats-together (family-of-N seat finder) - not implemented
• flights award-watch (award fare-drop watcher) - not implemented; track manually by re-running flights award-cheapest on a schedule
• atmos status (tier progress) - not implemented; use atmos-rewards balance for raw points
• flights search multi (multi-leg composer) - not implemented; run separate flights search invocations per leg
• doctor --auth (dedicated JWT decode flag) - not implemented; doctor performs the general auth check

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Agent-native plumbing

• flights search --select — Generic --select flag narrows the ~50KB search/results JSON to just the fields the agent needs.

  Lets the agent ask for exactly what it needs and skip the chrome.

  alaska-airlines-pp-cli flights search --origin SFO --destination SEA --depart 2026-11-27 --json --select flights.flightNumber,flights.fares.saver.price,flights.duration
  

Award (miles+cash) planner

• flights award-cheapest --destination-region japan --month 2026-08 — Fan out across every (depart, return) pair in a calendar month across multiple destination airports in parallel; return the cheapest round-trip in miles.

  Solves "find me a flight to Japan using points lowest price in August" in one command instead of clicking the Alaska site N times.

  alaska-airlines-pp-cli flights award-cheapest --origin SFO --destination-region japan --month 2026-08 --cabin economy --max-stops 1 --json
  

  Built on the same /search/results/__data.json endpoint the cash search uses; the --award flag (or flights award-search) toggles ShoppingMethod=onlineaward.

Cash vs. points value comparator with TPG valuation

• flights value-compare --origin FCO --destination SEA --depart 2026-08-30 — Runs paired cash + award searches for the same itinerary and applies a cents-per-point baseline (default: Alaska/Atmos from The Points Guy's monthly valuations page, scraped on first use and cached locally for 30 days). Returns effective cpp, TPG multiple, and TPG-valued dollar cost of paying with points.

  Answers "is this redemption actually a good deal?" in one read instead of running two searches and a calculator.

  alaska-airlines-pp-cli flights value-compare --origin FCO --destination SEA --depart 2026-08-30 --cabin economy --max-stops 0 --json
  

  Use --cpp 1.2 to override the baseline (e.g. NerdWallet's number) or --no-valuation-cache to force a fresh TPG scrape. Soft-fallback chain: override → fresh cache → live TPG → stale cache → constant. Never hard-fails on a valuation lookup issue; surfaces the source in meta.cpp_baseline_source (tpg-live, tpg-cached, override, fallback-stale, fallback-constant).

HTTP Transport

This CLI uses Chrome-compatible HTTP transport for browser-facing endpoints. It does not require a resident browser process for normal API calls.

Command Reference

account — Login status, session tokens

• alaska-airlines-pp-cli account login-status — Check if current cookie session is authenticated
• alaska-airlines-pp-cli account token — Refresh primary session JWT

airports — Airport lookup, codeshare partner info, and full catalog

• alaska-airlines-pp-cli airports get — Get airport details by IATA code, including codeshare carrier coverage
• alaska-airlines-pp-cli airports list — Full Alaska Airlines + codeshare airport list (IATA + city + region + lat/lon)

atmos-rewards — Atmos Rewards loyalty program account data

• alaska-airlines-pp-cli atmos-rewards balance — Current Atmos Rewards points balance
• alaska-airlines-pp-cli atmos-rewards token-refresh — Refresh Atmos Rewards token via cookie session

cart — Cart state for a constructed itinerary deeplink (read-only inspection)

• alaska-airlines-pp-cli cart — Inspect cart state for a constructed itinerary deeplink (requires --leg1 and --adults flags)

flights — Search Alaska Airlines flights with pricing, fare classes, and flexible-date matrices

• alaska-airlines-pp-cli flights business — Alaska for Business program metadata
• alaska-airlines-pp-cli flights et-info — Electronic ticket info / general metadata
• alaska-airlines-pp-cli flights get-features — Feature flags scoped to a user (used internally by site)
• alaska-airlines-pp-cli flights search — Search flights between two airports for given dates and passenger mix. Pass --award to switch from cash to miles+cash fares (same endpoint, ShoppingMethod=onlineaward).
• alaska-airlines-pp-cli flights shoulder-dates — Flexible-date pricing matrix - get fares for dates near your target
• alaska-airlines-pp-cli flights award-search — Single-date award fare matrix (miles + cash). Thin alias over flights search --award.
• alaska-airlines-pp-cli flights award-cheapest — Lowest-miles-in-a-month planner. Fans out across destinations and (depart, return) pairs in parallel; returns the cheapest round-trip in miles.
• alaska-airlines-pp-cli flights value-compare — Cash vs. points comparator with TPG cents-per-point valuation. Runs paired searches for the same itinerary and emits effective cpp, TPG multiple, and TPG-valued dollar cost of paying with points. Pass --cpp <float> to override the baseline.

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

alaska-airlines-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Recipes

Trim a flights search to just price and flight number

alaska-airlines-pp-cli flights search --origin SFO --destination SEA --depart 2026-11-27 --json --select flights.flightNumber,flights.duration,flights.fares.saver.price

Cuts the ~50KB results payload to just flight number, duration, and saver fare. Avoids dumping the full payload into agent context.

Family search round trip

alaska-airlines-pp-cli flights search --origin SFO --destination SEA --depart 2026-11-27 --return 2026-11-30 --adults 2 --children 4 --json

Round-trip fare matrix for two adults and four children across all cabin classes.

Flexible-date pricing matrix

alaska-airlines-pp-cli flights shoulder-dates --json

Get fares for dates near your target departure so you can spot a cheaper shoulder date without N separate searches.

Award search for a single date

alaska-airlines-pp-cli flights award-search --origin SFO --destination HND --depart 2026-08-15 --return 2026-08-22 --cabin economy --json

Single-date miles+cash fare matrix. Same endpoint as cash flights search, just with ShoppingMethod=onlineaward. You can also pass --award to the regular flights search for the same effect.

Cheapest round-trip to Japan in a month using miles

alaska-airlines-pp-cli flights award-cheapest --origin SFO --destination-region japan --month 2026-08 --cabin economy --max-stops 1 --json

Iterates every (depart, return) pair in August across 8 Japan airports in parallel and returns the top-5 cheapest round-trips by miles. Use --min-nights and --max-nights to bound the trip length (default 5-21 nights). Use --top-n to control result count, --concurrency to tune fan-out, and --save <path> to persist the full result set, not just the top-N.

Cash vs. points comparison with TPG valuation

alaska-airlines-pp-cli flights value-compare --origin FCO --destination SEA --depart 2026-08-30 --cabin economy --max-stops 0 --json

Runs paired cash and award searches against the same itinerary, scrapes TPG's monthly Alaska/Atmos cents-per-point on first use (cached 30 days), and emits an apples-to-apples comparison. Output meta surfaces cpp_baseline_source (tpg-live, tpg-cached, override, fallback-stale, fallback-constant) so the agent can audit baseline freshness.

Override TPG with another source's valuation:

alaska-airlines-pp-cli flights value-compare --origin FCO --destination SEA --depart 2026-08-30 --cpp 1.2 --json

Atmos Rewards balance

alaska-airlines-pp-cli atmos-rewards balance --json

Current Atmos Rewards points balance for the cookie-session account.

Airport lookup

alaska-airlines-pp-cli airports get --iata SEA --json

Pull airport details (city, region, lat/lon, codeshare carriers) for a single IATA code from the local store.

Auth Setup

Run auth login --chrome once. It extracts Alaska's cookies from your logged-in Chrome profile (AS_ACNT, AS_NAME, guestsession, ASSession, etc.) via your macOS keychain. Future commands replay them via Surf transport with a Chrome TLS fingerprint.

Run alaska-airlines-pp-cli doctor to verify setup. doctor performs the auth/reachability check; the manuscript's planned dedicated doctor --auth JWT-decode flag is not implemented in this generation.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

• Pipeable — JSON on stdout, errors on stderr

• Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

  alaska-airlines-pp-cli airports list --agent --select id,name,status
  

• Previewable — --dry-run shows the request without sending

• Offline-friendly — sync/search commands can use the local SQLite store when available

• Non-interactive — never prompts, every input is a flag

• Explicit retries — use --idempotent only when an already-existing create should count as success

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

alaska-airlines-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
alaska-airlines-pp-cli feedback --stdin < notes.txt
alaska-airlines-pp-cli feedback list --json --limit 10

Entries are stored locally at ~/.alaska-airlines-pp-cli/feedback.jsonl. They are never POSTed unless ALASKA_AIRLINES_FEEDBACK_ENDPOINT is set AND either --send is passed or ALASKA_AIRLINES_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

alaska-airlines-pp-cli profile save briefing --json
alaska-airlines-pp-cli --profile briefing airports list
alaska-airlines-pp-cli profile list --json
alaska-airlines-pp-cli profile show briefing
alaska-airlines-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.
