It's been a while since dh and I have been abroad so we are bickering over this. He says we should check in online. I said it's pointless when we have bags to drop off for the hold as you still need to queue up to check those in and might as well do it all at once. We also don't have a printer so wouldn't be able to print off our own boarding passes anyway.
I understand it makes it quicker for people who just have hand luggage and can therefore bypass the check in desk but what's the point in doing it if you have suitcases?
