I've not travelled on a plane for 15 years so am not up to speed on everything, so was super careful to ensure that the bags I got were specifically to size. I flew RyanAir on the way out and I'm just about to get on a plane with Jet2 coming home. I was measuring and stressing that I was a cm out and bought new bags and cases. Turned up at the airport and all sorts of sizes are breezing through. Same now on the way home. What have I missed? Is it just so that they can pounce and charge more if they feel like it? I mean there are people here with more than one bag, carriers not from duty free etc etc. Am I being unreasonable to say if that's the size - that's the size? I'm really confused. 🤔
