I've got a round trip BHX-DUB-BOS coming up, and the return DUB-BHX is operated by Stobart Air, which shows a smaller cabin baggage allowance (48x33x20cm vs. 55x40x24cm). As I suspect this is down to size of bins on the ATR, what is the likely outcome of turning up at the gate with 'regular' size carry-on that would have been OK on previous A330 operated sector?
* Charged extra to check in carry on
* Asked to gate check with no charge
* Nobody notices and hope to fit it in bins
* Thrown in jail?
