You also have to check in at the airport (not on the APP) if you have basic economy. They don’t say this at any of their website. But they will make you physically line up to check in.
There are codes next to economy for my flights, and I have no idea what they mean. What does "H" and "V" mean? Are these economy or basic economy? I want to bring a carry-on plus a personal item, but I don't want there to be a problem.
