Hello, I had a mixed experience with Aeromexico Airlines SFO Terminal. It took a long time to get through the line, but the check-in desk staff was polite. There were decent dining options close by, and the terminal itself was tidy and well-kept. The speed at which security moved was a bonus. There wasn't much sitting in the gate area, though, and it was packed. The flight staff made up for the somewhat chaotic boarding process once they were on board. Although it's not the greatest terminal I've ever flown from, it's also not the worst. Just be ready for some chaos when you're boarding at the gate.
