Check in process was terrible. Lady at counter didn’t know what she was doing

Check in process was terrible. Lady at counter didn’t know what she was doing

Delayed and took off even later than the scheduled delay time

For a 69 year old with health problems I had the worse experience, no wheelchair when I entered a lady told me to sit and wait while a gentleman told me I had to walk to the Delta station, which I did. I had a carry on and a bag, and I was traveling with my service dog, which was on his carrier and the lady charged me for my carry on luggage, beside all the waiting cause of the delay, I had to walk to get my luggage cause no wheelchair showed up, I am so disappointed. I will get in touch with the company. I got home at 3:00 am, not good for my health situation.

Great experience on Delta. Staff from baggage check to flight attendants were very courteous and professional. My only issue was a personal preference for pretzels instead of the chips and cookies that were offered.

The crew was amazing; Von, Vera and Guadalupe were very friendly and attentive throughout the entire flight. They were friendly and welcoming to everyone. A solid and dedicated team for sure!

Terrible. I was bumped off of my original flight and spent the next six days fighting to get back on it. I lost hours of my vacation trying to get this situation corrected.

There was no problems, just a little uncomfortable with seats that do not lay back a little

Always good but we must do something about people in rows ahead of you that don't put their seats back up when they are suppose to. And It's rough to not be able to even lean over to get something out of my purse.

Flight was delayed, 30+ bags had to be gate checked. Crew were very friendly!

Everything was good until we were boarding our connection flight in Atlanta, we were told to gate check our carry-on, but when we got inside the plane, there was plenty of room in the overhead.

Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.

Overall it was good. I missed my connection but I was put on another flight.

Overall a very poor experience - booked premium economy tickets but due to last minute flight delays , all my itinery went for a toss and had to fly economy class with no access to lounge or any compensation by united airlines to make up for the flight delays . i had expected better experience than that from united.

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

All flight attendants could benefit by taking an international flight on Qantas Airline. Qantas attendants are much more hospitable in every way. Much superior than and attendants on any US airline.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

The first flight was better in terms of the aircraft.

So far so good but food and entertainment are not available for this flight

Im if Ethiopian can allow customers to use their mileage for in flight connexion it will be great.

United was best airlines I have seen since I got there choose united airlines

It was wonderful best Air lines covert and all very happy with their service they have been very helpful and friendly

It was very bad experience with Ethiopian airlines . The flight was delayed in both ways . On the way coming back one of the crews dropped hot coffee on my whole body and other crew dropped used dirty glasses on top of me . The same crew that dropped hot coffee on me hit me with the food trolley on my knee while I was sleeping . I couldn’t sit properly due to the pain on my knee caused by those irresponsible crews . Very unprofessional airlines

Flight was delayed an hour. Also, I bought an extra legroom seat online; but the actually plane was a different configuration so I didn't get what I paid for . This happened on the Addis to Lusaka leg of my trip.

Needs improvement because some of the tvs and charging ports weren’t working

The plane was overbooked and the crew was very rude. My luggage was never put on the plane. I got to NY and waited 2 hours just to find out that my luggage was left.

Very bad experience flight was over 5 hours delayed 😑 not a chance to be put on another flight we had to stay at the hotel we lost 2 days on our vacation. Never again I will fligh with Ethiopian airlines.

Terrible customer service I lost my bag luggage and I still haven’t received any information

The ailine departed and arrived late foe every leg of the trip, causing myself and my travel companions to miss every connecting flight. It was very unorganized given theat there was a lot of miscommunication. The flights offered are unrealistic and when you call they assure you that the plane waits for you. I missed an. entire day of my vacation and any entire day of rest back home because of the airline. I do not plan to support the airline again. Thank you
