# Later Dates

`POST /conv/flight-offers/calendar/later`

## Request

- Base URL: `https://api.helloaxel.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.helloaxel.com/conv/flight-offers/calendar/later`
- Auth: none declared

A route's departures after its calendar's 90 days: the lowest published price per pair of dates.

## Request body

- GeneratedFlightLaterDatesQuery: The departures after a calendar's 90 days, in one read of price-only rows. Its own model, not the calendar's query: the calendar's window rule, its overview and its longer stays do not apply here. Stays are the calendar's standard 1 to 14 nights.
  - `origin` string, required
  - `destination` string, required
  - `departure_date` string, date, required
  - `days` integer
  - `minimum_nights` integer
  - `round_trip` boolean

## Response `200`

Successful Response

- GeneratedFlightLaterDates: Published prices for a route's later departures, lowest per pair of dates. The calendar read returns full fares, about a megabyte for 90 departures. A page that lists later departures needs only what the calendar would show for each pair of dates: the lowest price with its airline and, for a round trip, the second choice. This answer carries those and nothing else. Amounts are the published model prices: a live check saved for one exact trip shows on that trip's own page, not here.
  - `issued_at` string, date-time, nullable, required: When the route's published prices were issued. Null with no later date to list.
  - `services` GeneratedFlightLaterService[], required
    - `airline_code` string, nullable, required
    - `airline_name` string, nullable, required
    - `stops` integer, required
    - `connection_airports` string[], required
  - `days` GeneratedFlightLaterDay[], required
    - `departure_date` string, date, required
    - `one_way` GeneratedFlightLaterPrice, required: The lowest published price for one pair of dates: the calendar's first choice.
      - `amount` integer, required: Published USD total in cents; one adult, economy.
      - `services` integer[], required: One index into the answer's `services` per leg, outbound first.
      - `nights` integer, required: Nights before the return flight; 0 for a one-way.
      - `alternative` GeneratedFlightLaterOption
        - `amount` integer, required: Published USD total in cents; one adult, economy.
