Through Monday, April 11, 2016 The airline is still offering the exact same six flights a day from CLT that it is now: 2 x Baltimore, 2 x Chicago Midway, 1 x Dallas Love Field, 1 x Houston Hobby. (The Dallas flight started this past Sunday, replacing a summer-seasonal second Houston flight.)
Southwest also offered this past March a Saturday-only service to Orlando. Apparently that didn’t do well as it’s not being offered next year.
We should find out whether the second Houston flight returns for next summer in a couple months.
