I'm flying JFK-IAD on United soon. I'm bringing a whole lot of stuff with me in two large bags. One of them is just a large suitcase packed with as much clothes as it would hold. The other bag is an inflatable duffle bag on wheels. When full, the duffle expands in volume quite a lot. Basically, we packed it today and it weighs 45 pounds but is larger than the 62 inches that United says is the maximum size on their website.
So my question is what will happen when i check-in? Will they charge me a fee for the large bag (even though it's not overweight), or will they not let me check-it in at all? Or will it not be a problem?
Also, the JFK-IAD flight is on a Regional Jet. Not sure if that factors in...
Any help is appreciated.
