Flight from Chicago O'Hare Airport to Los Angeles

StephanieFlew with Spirit AirlinesORD-LAXApr 2025

Don’t go to LA and definitely don’t go to LA on Spirit. If I could give negative stars, I would.

MikeFlew with American AirlinesORD-LAXSep 2024

Arrive early, grab a bottle of soda before getting on the plane and open it in the terminal. If you wait until flying the pressure will decarbonize the drink.

GerryFlew with United AirlinesORD-LAXJan 2024

The one unfortunate item with this flight, because the flight was full, everyone in group 3 and more had to tag their carry on luggage and have it checked. I my opinion, there was lots of available space on the plane for pack packs, coats etc that could all have been put under the seat. We cannot give up our carry on because of the medical needs
