Guys - I've heard Iceland air can be a pain with carry-on luggage. Their website has listed 22lb 21.6x15.7x7.8in and all our carry-on's are 21 x 13.5 x 9 inches. It seems this will be an issue due to the last dimension. Do they do a test check if it fits before TSA security or at the gate? I'm fine if they force me to check in at the gate but if I have to pay. $69 per bag or $276 total and then same for the return trip, that'll kill our budget

Thanks
