As you know, Southwest Airlines has never charged dreaded change fees but all other domestic airlines have for quite some time.  This all changed in early September when United announced they are eliminating change fees for all domestic flights (except for Basic Economy tickets) AND to Mexico and the Caribbean.  Other large carriers – American, Delta, Alaska and Hawaiian Air have followed suit with some slight policy differences.  This coupled with low fares and greatly improved onboard cleanliness procedures makes for an ideal time to reserve your next vacation!
