If I book a flight + hotel deal on Expedia, then want to change to a different airline (after researching the airline company that was booked, they have some very unfavorable reviews), but it is not possible at this point to change airlines on Expedia.
If I purchase a new set of airline tickets on a different website for the same dates and use those to travel, what are the consequences with my trip? Will Expedia know I did not use the flight tickets booked on their site and is there any penalty for this?
