You can now tell whether an offer or order is changeable or refundable

For every offer, order and slice we now return a conditions property that lists the fare conditions that apply (where available). Within each condition you can now tell whether it is allowed and also what penalty fees will apply if that action is taken.

To start we are exposing change and refund conditions that apply before the departure of the first flight, and we've launched with support for British Airways. American Airlines and Lufthansa Group are next on the list.
