My flight experience was generally good, but the boarding process was stressful. I was pulled out of line at the gate during the photo ID check, and after being cleared, I was never given an explanation for the delay despite asking for clarification. This lack of communication was the only downside to an otherwise smooth trip.
Staff is friendly and helpful but flight was delayed by one hour from Detroit, making for tight window in Toronto to clear Canada Customs and pass through security screening in order to get to connecting flight on time.
I was in first class and literally the men behind me were so aggressively loud I moved myself to economy. This has become so common on Delta - people using audio without headphones, and men on 12am / late night flights drinking and yelling to talk to each other which prevents anyone around them from resting. Pretty crazy to have to move from first to economy (poorer service, less comfort...). Wild wild. Looking into other airlines.
After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.
Rode in a smaller plane and short trip meant no snacks, no free wifi or tv. It was only 30min flight so honestly wasn’t a big deal to lack these items.
We were forced to wait nearly 50 additional minutes before leaving the terminal.
I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine
Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!
Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska
Perfect. On time and the weather was perfect so we came in a few minutes early.
Upset about cancel to St. John’s and no overnight accomodation
1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.
Entertainment kept turning itself off. Gave up on watching a movie.
Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back
Not United Airlines' fault. It's ORL airport's fault.
I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.
Backpack should NOT allowed put in the flight bin , only put it under the seat. I can't find space put my carry on luggage!!! and I pay for it ! that was very bad experience
Flight was fine, it was delayed but only 30 minutes, staff were efficient, lady making announcements at LAX was really hard to understand but the rest were great.
A good, solid, no frills experience. Departed and arrived on time, staff were pleasant and attentive. Loved the Bluetooth connectivity on the SJC to IAH leg. Being able to watch movies and listen to them with my noise cancelling headphones was lovely. Missed that on the IAH to LHR leg (so I put the wired buds on and my over ear Quiet Comforts over those).
