| I have never had issues with this airport. I have flown in and out of Bush for years now. I had a flight that departed IAH at 5.15am on Saturday morning. I arrived at the airport early, as I always do, just in case something unexpected happens. I guess I should've given myself four hours because the line to get into security was around 200 people deep with only one TSA agent verifying tickets and identifications. I waited in that line forever. Then, my flight was scheduled to leave in 10 minutes. I knew I wasn't going to make it because there wasn't enough staff to accommodate the growing number of passengers entering the security line. There was another TSA agent, but he was just sitting there helping the small line of TSA-Pre Check. When there wasn't anyone in the Pre-Check line, he just sat there in his chair and didn't even bother helping the growing line. Once I got up to the TSA agent, she met me with anger. She was rude and didn't even communicate to me with words! She just motioned me to move to the side without any explanation. I had to wait another 10 minutes, and by that time, my flight had already left the gate. I am very dissatisfied with my experience. Why was there only one TSA agent? I'd probably be rude to customers too if I was the only one working that terminal with a line of 200 people and growing. If you're going to the airport, just remember to be there maybe about six hours before your flight, because you never know how short staffed they will be on any given day.
