I have checked United's website & I already know my first bag is free up to 50 lbs. If I had status, it would be up to 70 lbs. I am going away for 2 weeks so I may go over 50 & was wondering what the fee would be. Upon calling United, they informed me the fee was $200 for a 51 lb bag, but a 50 lb bag would be free. This sounds bizarre. Is there no surcharge fee that exists between 50 and 70 lbs for non-status flyers? The route is ORD - EDI. Thanks.

Also, as a side note - I've been slightly over 50 lbs on Aer Lingus & over on their carry-on limit a few times and they just shrug and say "looks like 50 to me" and let me go. I don't know if United would be the same way.
