Hand Luggage [Bag 3cm over max - will I get away with it?]
I'm flying EDI-LHR-SIN soon and I would like to take my bag onboard with me but it is 3cms over the maximum length. Will I get away with it or have to check it in as I don't like to risk it being transferred from T5 to T4 and really don't want to arrive in SIN with no luggage.
Thanks
