FlightNumber

A flight's code: BA123.

Use it for a passenger's flight. For the airline alone, use IataAirline.

Shape

Write every field when you build one, and give a field that isn't required as none.

Example

FlightNumber { airline: "BA" number: 123 suffix: none }

text.parse(raw, as: FlightNumber) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as BA0123, BA 123 or ba123.

Good to know

• The number runs from 1 to 9999, and it has no leading zeros, so BA0123 is refused.
• == tells you whether two are the same. < and list.sort_by don't take it, so sort by one of its parts instead.

In JSON

A string, in a request, a response or json.write:

"BA123""U21234""6E2001"

When you read one, a field that isn't required may be left out, or sent as null.
