Before you fly on Firefly

Two things move a cabin limit after it has been published: the fare family and the route. A carrier can sell a bundle that raises the weight without touching the box, and a regional sector can be trimmed below the long-haul figure. The number on this page is the published economy short-haul number, dated October 2026.

Measure your own bag with a tape, then run the three sides through the assessment box. If the bag clears by a centimetre, pack it soft; if it clears by five, the frame is not the risk — the weight is.
