Make sure you are at the airport at least 3 hours early to ensure that you can check in, go through security, and so that you can find your departure gate within plenty of time so you are not rushing.

By your own food and have your own music. Upgrade your seat if you have the funds!
WendyFlew with IberiaLHR-PITJul 2024
This is a good service to a smaller gateway airport. It's usually full. This service is why we selected BA. If you've prepaid for your seats be prepared for them to switch the plane configuration and reassign your seats. You'll have to apply for this refund too since it's not automatic. These refunds should be automatic not a chore for you to get your money back, especially when you have selected seats you personally want.
Anne KatherineFlew with IberiaLHR-PHLJul 2024
Need more snacks. As meals not big and need more to eat Also take own water on board as not enough drinks offered from cabin crew - can feel dehydrated during flight
SuzanneFlew with British AirwaysLHR-PITMay 2024
1 - bring a portable battery backup because you can't rely on the outlets at your seat to be working. 2 - download movies/shows to your device, because you can't rely on your headphones or screen to be working. 3 - download any work, as possible, to your laptop, because you can't rely on WiFi to be working.

bad… no veg food was provided eventhough i pre ordered special meal

Excellent service provided the flight crew. Food and drinks were very good.

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~

I was really impressed with the experience it was my first trip overseas. Nice staff

Not enough food for everyone. . Always run out of food when we ask

Customer service was exceptional. I heard it wasn’t a great airline, my opinion has changed after flying with them

The crews were smiling all the time with soft tunes when they spoke; the food was excellent. Thank you!

Cathay flight was fine, Amsterdam airport was a nightmare, spent way too much time walking to our next connection, no travelators.

They charged me $900 to board my flight I already paid for just because I missed my previous flight. I do not recommend this airline by any means.

As a solo traveller, I always prefer to have an aisle seat, but the flight was so full, there weren’t any available. I understand that the seatbelt sign sometimes has to go on if turbulence is anticipated but after the second food service, it was on continuously for about an hour and a half and there didn’t seem to be any turbulence at all! With seats reclined, my fellow passenger in the aisle seat asleep and the seatbelt sign on I felt very trapped, extremely uncomfortable and in desperate need of the bathroom. The positives were that the staff were very friendly, the entertainment was great and we actually took off on time and arrived in HKG earlier than expected.

Our check-in was mediocre. We were told that we didnt have access to the lounge although we were in business and we were asked to remove 1kg from each of our checked luggages as they had 21 kgs and we found out that our tickets were for 20kgs checked bags. I would have expected: 1 - more clarity on the website so that I could see the difference on fares and be able to buy tickets with more checked luggage kgs allowance, and lounge access, and 2- more flexibility for business class passengers.

On the flight back the seats where very uncomfortable, they where so bad that my back started to hurt after the first 2 hours. I can sit in a wooden chair for 2 hours. But these where just horrible, it just shows how cheap the airline has become. And the cabin was heated all those people in a heated cabin during a night flight. It was clear the climate control was not working. To top that off you are not even offered a glass of water, these people are animals.

We purchased a Go First Pass for 10 Euros each so we could board first, but everyone was able to board at the same time so we wasted 20 Euros. The flight left ab out 15 minutes late and was not allowed to land at Healthrow so we had to circle Heathrow for about 45 minutes. This caused us to almost miss our flight from Heathrow to Atlanta.

Severely delayed with no notice. Could have arrived at the airport hours later had we been informed of the delay

Once the boarding sign went on and all passengers gathered in line, we were left waiting standing up for almost an hour because there was a delay.

It would be nice to have vegan options for meals. The entertainment was not working on the the way to Austria. It was only available near the end of flight to Canada. The service was excellent.

Flight was delayed by approx 1 hour. The boarding process and the flight itself were very good, slightly tight squeeze for my legs but overall happy.

The business class layout on this plane is tightly packed and atrocious with no sense of privacy.

Flight was meant to leave at 8:30pm but there was a 2 hour delay 😞

Airmalta does not include meals in their flights and neither offers entertainment.

We boarded and then sat on the tarmac for an hour….probably not E Jets fault. But the gentleman that checked us in and took our luggage was exceptionally friendly and calming for early morning/ confused passengers. As always, it’s the people that make or break an experience, right?

Kayak sent several notifications that the flight was late. This contradicted the information on the airport boards. This was extremely confusing and we very nearly missed the flight purely because we double checked with the info desk when the flight stays said’closed’. Kayak notifications are therefore unreliable and pointlesa

Delayed almost 2 hours sitting on plane. No updates at all from flight deck and virtually no updates from cabin crew

Long delay resulted in my being unable to catch a train home and resulted in an additional £76 cost for an Uber

Be sure to check bags for 23 kg,.(50 lbs) Coming from US I chose the wrong size luggage weight when I checked in on my phone, and had to pay more when I dropped it off

The flight was delayed for over 1 hour. The boarding process is appalling making you wait for 30 minutes in the passage leading to the outside door without any seats.

All around poor experience. Barely got on flight because it was ostensibly overbooked. Forced into checking a carryon bag with empty overhead compartments. Nickeled and dimed. Charged for coffee. Despicable.

The on board air steward really made the journey. He was very entertaining

I was disappointed there was a 40 minute delay to flight

They cancelled my flight and we had to fend for ourselves to reschedule another flight. There was no staff to help all the canceled guest. Poor communication and staff. I attempted to reschedule via Kayak and I asked their staff that it looked as it was available. The guy behind the counter just told us to go online..

We were diverted to warsaw and there was zero information. We were just forced to disembark and off we go good luck the reat of the way. We all had to go our ways to find a way home!!!! Horrible horrible and it cost us alot of money to get a hotel and trains 4:30 pm next day.

Long delay was made worse by lack of information and long time in queue waiting for the plane to arrive

Blood contaminated tissue was stuffed to the back of the seat in front of us.

Great flight, departed only 10 mins behind schedule off the aircraft and through security in less than 15 minutes. Love flying from Cardiff so easy a quick from entrance to duty free in less than 10 minutes 😀

You have improved through the many years I have flown with you. But you still nickle and dime your customers. I paid extra for carry on and priority boarding.

My flight was delayed 1 hour. My Mood was not great

Lord knows why they had us start boarding when the plane wasn't even there, staff weren't welcoming and the couple next to me travelling with a young child had a nightmare with the baby changing facilities.

This time round it was very good, flight delayed by 30mins but capitan put his toe to the floor and made some time up!!

Boarding at Birmingham was appalling, made to stand in a corridor which claims to be a gate for an hour, despite knowing full well the flight was delayed….. the crew were fantastic and you have to feel sorry for them dealing with the delay caused three fold, inbound delay, damage to front baggage hold door and finally a further ATC delay. On board experience was good and crew friendly and helpful.

Flight was good but delayed (45 minutes) which made other connections difficult.

Flight was fine, food better than anticipated and flight attendants were helpful and friendly.

Our headphone plug is broken, we can not enjoy our entertainment, especially traveling with 5 year old who like to watch movie

Pleasant, attentive and efficient flight attendants. Boarding process and seat selection easy. No internet on transatlantic flight. Extremely uncomfortable, rigid seat.

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

They had about 20-25 people overbooked. Including me. Why is this?? I was put on a flight to NC an hour later with a 4 hour layover. I was supposed to be home at 1045am instead i was home at 7:30pm. An extra day to pay for dog care.

Boarding is not controlled as groups called was not enforced

The plane was clean. The crew were lovely. Food was good - but seat 1D is a poor location. - the crews cupboard is right near your feet and they visited them frequently swishing the curtain from the galley onto my feet everytime also creating a swish of cold air each time & then slamming the door.

Horrible food and uncomfortable plane. One toilet was out of service.
