Hi, I was wondering if anyone has flown recently on the E-175 aircraft. I've never flown Air Canada before and I'm supposed to be connecting through Toronto on the way to Europe for a cruise in September, assuming it doesn't get cancelled. I would like to travel carry on only but this will be challenging for a 7 day cruise. Do the standard American size carry on rollaboards fit in the overhead bins on this aircraft (21" spinner size)? If they don't fit or if the bins get full, do they gate check and you can pick up in the jet bridge or do they totally check to your final destination? Thanks so much!
