How is it that hopper has checked baggage fees on many routes where the airline that flies the route or most other 3rd party travel site do not charge a checked baggage fee. What a rip off, & capitalone travel is powered by Hopper so you will see the same greedy practice on capitalone travel. I hope capitalone travel drops hopper. Response to Hopper: I didn't book w/ hooper because the airline and other sites don't charge this fee. Only you do. Try an US-europe route such as JFK-WAW.
