Late like always. Harassed over the new luggage policy even after paying for our bags. Online check constantly badgers you to buy bags, buy the perks, and book extra things like cars and hotels. Don’t bother unless you are traveling on a day trip. After luggage fees you pay more than Southwest with terrible service and always late.
