It was a great experience, friendly staff and good snacks

It was a great experience, friendly staff and good snacks

Apart from the man snoring very loudly across the aisle from us for about 3.5 of the 5 hour flight it was a great flight. I couldn't get the internet to work and stay working. Texting was intermittent for me.

This was our first time flying with Alaska. It was a seamless experience, with comfortable seats and leg room. Staff were friendly and helpful.

Flight delay caused me to miss my connecting flight home, but I was put up at a nearby motel, and it was great

Flight on time. Crew good. Seating Bad. Have to pay extra on a not cheap flight to avoid being next to toilet.

The plane boarded late and arrived late which wasn't really ideal.

Online check in didn't work. Somehow ended up with 2 Alaska rewards numbers and 1 for Hawaiian. No one at check in could figure out what to do. No one at check in could help me confirm an upcoming flight on Hawaiian Airlines.

This was more with the third party booking through Kayak but my KTN for Pre-TSA, even though I entered it, wasn't assigned to my ticket when I got to the airport. I had to go through regular security. Also the Alaska app had trouble loading my ticket in the first place and I had to ask for it to be printed. Alaska Airlines was great but wanted you to know about this hiccup in the ticketing interface.

The crew was great! Passengers were nice. Just an fyi that I heard several of them complain that the snack was not gluten free. Many people got handed the snack and then promptly gave it back to the flight attendant. Might be good to look into another option as such a high percentage of people in CO and WA are gf. Cheers!

Flight was delayed 14 hours! We missed an entire day of our vacation and had to pay for hotel that we didn’t use

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

Same as last comment. Food sucks. Quality. Not surprising most people have no clue about nourishment Clearly

Not the fault of United—weather, reroute around weather, time sitting on tarmac, arrived couple hours late, too late for train into city necessitating a much pricier cab but weather…can’t be helped.

Friendly and professional flight crew. Aside from departure delay after boarding, easy flight and smooth landing.

Great smooth flight. Had a seating change, but that was an improvement. Thanks United Airways Crew.

The flight attendants were great, I joked with one I can’t remember her name, a blond, really sweet. I thought it was run well very professional. This was great i survived Spirit, I know for which I speak.

My husband and I recently had an unfortunate experience with Lufthansa. At the Philadelphia International airport, the ground staff refused to board us because we didn’t have a current visa stamped on our passports for Frankfurt. We completely understand that this was our mistake. we should have double-checked the visa requirements before our trip. However, the issue that upset us most was how the situation was handled by the staff. They told us they would mark it as “boarding denied due to visa issue”, but instead they recorded it as “no show”. Because of that incorrect entry, our return flight was automatically cancelled as well, which caused additional stress and expense. Mistakes can happen, but we expected more transparency and accuracy from a reputed airline like Lufthansa. It would have made a big difference if the staff had been more careful and considerate in documenting the situation correctly.

Flight was good but there are way to many announcements for credit cards etc.
