Flight was delayed and no reasons provided. After the passengers were boarded, the crew made announcement that the captain has jot arrived and he would take another 15 mins. All passengers patiently sat until the captain came and started. Terrible experience!

Flight was delayed. No information on why it was delayed. After we boarded the flight, , the crew made announcement that the captain hs not arrived and he will take 15 mins more to arrive. Passengers were just sitting patiently for the captain to arrive and start, Terrible experience.

2.0 Poor

Shebani, Feb 2026

Awful - both legs. The check in was awful, getting on the plane required walking down a spiral staircase (dangerous), then taking a bus about 5 miles out from the terminal. The seat was broken (I was in business), there was no internet during the flight (both legs). The aircraft was very old. I saw rust in some place, tape holding things up in the bathroom. This was an unacceptable experience for such a long haul flight.

Totally worth the miles to upgrade to Delta Comfort. Plenty of legroom.

Russell, Feb 2026

Smallest leg room I've ever had on a plane.

4.0 Mediocre

Duane, Feb 2026

They took all carry-on luggage from Groups 6 -9 - I was group 5 and waiting in line to board - they made me check my luggage too. That then went to baggage claim and delayed departure from the airport. There was overhead room in my seating area - Delta over reacted. Also, had a gentleman next to me that took up 1/2 my seat.

8.0 Very good

Very good, staff was pleasant and helpful.

Edgar Otto Enrique, Feb 2026

Excellent!!! Aeromexico is a great airline. What was not that good is the service provided by Kayak. It is never clear and not easy to manage.

6.0 Okay

Nikhil, Feb 2026

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors
