I am flying from Houston to Abu Dhabi in Economy. Flight is sold by Etihad but has an American Airlines leg from Houston to Chicago. Baggage Allowance is just 1 bag. Etihad website has an option to pay for extra baggage but would not let me since the first leg is operated by American Airlines.
I was wondering if I can check-in an extra bag with American Airlines at the airport after paying the surcharge. I hope I don't get denied checking in the extra bag at the airport.
Does anyone know?
