Flight arrived 30 min early and bag was waiting at the baggage pickup. United Club HNL was one of the nicest in the system

Unfortunately weather delayed our flight waiting for our plane to arrive and due to a little snow time was needed to deice the plane so departure was very delayed and I missed the connecting flight

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The flight crew where really good. Better then the crew from BNE to SFO

Food should be changed in menu Many muslims travels in this airlime they need to add one Halal meal

Delayed, toilets did not flush, pilot parked to far away from Gate

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Ineffective communication with United resulted in lost baggage. Their Baggage Tracing counter at MUC was shut down from 11:00-14:15 on my arrival. Undertrained, underinformed staff had me Running all over MUC to find someone to help me to no avail. Staff was rude, unhelpful, and unable to effectively use the systems they did have operational. They refused to contact United in any way or provide any accommodation or other resources while I waited for my luggage. This has destroyed my downstream itinerary. If they had even the slightest visibility I may have been able to reschedule/plan, but again, their staff provided nothing, and did nothing more than their website, which doesn’t even work on a standard phone browser. Miserable failure at all levels that weren’t associated with the operation of the aircraft.

One of the best flight experiences I've have had in along time. Would fly with them again.

Like - the crew were nice Dislike - sitting on the tarmac for long periods after boarding and landing.

Canceled my flight couple hours before takeoff. They could not find a decent re-routing and refused to pay for when i subjected alternative with Lufthansa.

Seats a little to soft on the SFO DUB flight

Well, I think we left close to on time. Crew was “eh”.

It’s my new favourite airline! Everything was smooth and relaxed!

Flight takeoff was delayed an hour, but arrival time was not updated at the same time as departure time, so those picking me up at the other end were not alerted to the change in my arrival.

Seats are terribly cramped. I’m only 5’2” and my knees were practically in my face. No room to put a normal size bag under the seat and when the person in front of you reclined their seat your tray table was in your lap. This is the airline’s way of cramming more seats into the plane to make more money. I’ll think twice about taking Aer Lingus again since there are a few other options from Boston to the Emerald Isle.

Couldn’t check In online, message was couldn’t check in until Sunday morning though plane left Saturday night. Checked in okay at airport but caused slot if stress.

The same as I stated prior. We incurred extra costs that should be reimbursed, given we were not communicated with about schedule changes.
