Hi! My family and I recently passed through the Southwest Airlines IAH Terminal and it was great. The check-in experience was fast and hassle-free, with courteous personnel eager to help. Security lines flowed well, a welcome relief while traveling with children. The terminal was tidy, roomy, and featured an abundance of seating. We also appreciated the array of dining options prior to our flight. Boarding was well-managed and punctual. Overall, the Southwest Airlines ensured our travel free from hassle and enjoyable. If you’re traveling with Southwest from Houston, I recommend this terminal to have a hassle-free experience!
