The first class flight attendant was awful to everyone. Very rude; no customer service. She should not be working in first class.
4.0 OkayKacie, Mar 2026
The first class flight attendant was awful to everyone. Very rude; no customer service. She should not be working in first class.
Smaller plane for a longer flight than my first one. Doesn’t make sense.
Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow
The whole experience was excellent. As it most often is with Delta
Cabin was not pressurized properly. Several passengers had respiratory difficulties.
Very Very late. Subsequent flights left an hour before ours
First flight out and was 85 minutes delayed. Notification came out way too late
Delta flights recently are always delayed AND at jfk tney get the gates further away (need To walk 20’ to get to them/all the way at the end of the terminal). Not sure whats happening but price doesnt match experience!
bulkhead seat had very little legroom - even in bsiness class.
The plane was an older model, so it wasn’t as comfortable as others. The flight attendants were not helpful during onboarding. It was a full flight so there was chaos finding space for baggage.
