Derek, Sep 2026

DL482 did not wait for about 10 of us including a mother and 3 children when we were in the same terminal on DL486, where we were switching from waiting for a jet bridge fix, to moving to a neighboring gate. I understand taxiing delays are ok either but man. We only needed 5 more minutes. DL482 did not adjust from their times at all. This was my first time with Delta.

2.0 Poor

Derek, Sep 2026

DL486 could not get to the gate due to jet bridge malfunction. We moved gates. The connecting flight of LAX to MCO was not communicated with. Even though we were in the same terminal, DL482 left without about 10 of us, including a mother and her 3 children. I got to the gate at 7:34 am which is past the 7:20 am last call for a 7:35 am departure. Had they waited 5 minutes, all of us would have made it on board.

8.0 Very good

Kevin, Sep 2026

The wait in the tunnel to enter the plane was too long. The counter personnel, specially ''Israel'' was really not welcoming considering Delta Standards. Other than this everything was good overall.
