Hi! Departing out of Delta Airlines IAH Terminal should be a simple, hassle-free experience. Delta flies out of Terminal A of George Bush Intercontinental Airport (IAH), which features a clean, well-maintained building and friendly service staff. Security lines tend to be well-arranged, and there are decent restaurants to grab a quick snack to eat prior to departure. The terminal itself is not exactly state-of-the-art, but it is convenient to get through and navigate. Delta Airlines IAH Terminal generally offers a good, dependable experience for travelers departing to or from Houston!
