The Flight Steward
Offline-first PWA for cabin crew to track first-class drink and meal orders by seat.
The need
Service in the premium cabin runs on memory and a paper pad during boarding, taxi and flight, when there is no connectivity. Flight Steward keeps every order on the device and works with zero signal.
What was hard
- 1
Offline-first storage
All data lives in IndexedDB with versioned schema migrations, so the app works with no signal.
- 2
AI screenshot import
A photo of the passenger or pre-order list becomes seat records, classified against a strict JSON schema.
- 3
Overlapping screenshot merge
Half-read rows from overlapping screenshots collapse into full ones, and spelling variants of one meal unify.
- 4
Seat swap state machine
A seat swap is modeled as an explicit state machine rather than ad hoc edits.
- 5
Fast ordering
Single-tap drink ordering over a drink catalog, meal inventory math and ranked name autocomplete keep service quick.
- 6
Quota and diagnostics
A per-user daily import quota and an on-device diagnostics ring buffer keep costs bounded and bugs traceable.
