Retrofit

The refitting of existing aircraft with a new cabin — the multi-year programmes by which announced products actually reach the fleet. Retrofits are why "airline X has suites now" is only half a fact: the new cabin may cover a fraction of the aircraft flying your route for years. The professional question is never whether the carrier has the product but whether your specific flight, on your specific date, carries it — and that is checkable, so we check it.
