Gate outcomeCarry-on that exceeds the limits at the boarding gate is offloaded to the hold. Staff can test-fit your bag at check-in, which is the moment to ask.Seat-only fares on some routes exclude a checked bag, so anything that fails the cabin check becomes a paid checked bag at the airport rate.

Our verdict: If a trip includes a Rex leg, that leg decides the bag. A soft 48 x 34 x 23 cm bag fits both airlines; a 55 x 40 x 23 cm Air NZ bag will not fit a Saab 340 bin.
