However, that would be done at the plane/gate, not at check in, so at least your bag wouldn't have to go through the trauma of the entire airport system.
On my last flight in April (with Jet2) there was some problem with the bridge to the plane, so I was able to watch the baggage taken off the plane before I was.

I saw my bag leave the plane before me.

But I saw how the handlers were handling things, and it wasn't that gently I can tell you. :shake: Not excessively rough, but things were flung, as they would have to be to get things off in a reasonable amount of time. When travelling I have all my camera gear plus laptop in my backpack, and I wouldn't trust the gear to survive the trip in and out of the plane hold no matter how close the the gate is to the plane. :nono:
I would rather they sorted all these things out at check in because at the gate there is more pressure to accept whatever they say, and you haven't been waiting for an hour plus just to be stopped at the last hurdle. :shrug:
Yes, you may get away with it, but you may not. :shrug: And then the staff may enforce the rules one way here, but differently at your destination. The uncertainty is the problem for me. I have a bag that was within their rules, but now isn't. My bag cost a lot, and is big enough for everything I want to take, gear wise. And now it isn't, what do I do, buy a new bag? But it won't be big enough for all my stuff.
And some are saying, well don't fly with them. This is fine when you live near London, Birmingham, Glasgow, very larg airports etc, because there may be other options, but your options are greatly reduced the further you are from a large airport. I was considering going to Lisbon, luckily Easyjet fly there from Liverpool, but Ryanair don't, and they don't fly there from Manchester either. And Easyjet and Jet2 don't fly there from Manchester either. BA don't fly from Liverpool, so it's Manchester, and it's from Manchester to Heathrow, then to Lisbon, and the outgoing flight is almost the cost of the whole flight from Liverpool. But this bag problem is putting me right off.
The bhakhsheesh levels are higher for getting camera gear back from holds too, in some countries.
"bhakhsheesh"?

:shrug: Had to have a look for what that meant. "Tipping, charitable giving, and certain forms of political corruption and bribery in the Middle East and South Asia" apparently, according to Wikipedia.
