We were charged a ridiculous amount for a name spelling error on ticket which I would’ve corrected if I received pre-check info more than 1/2hr before flight. Then we were told at ticket counter that our bags were fine for boarding but then we’re charged another ridiculous amount to take in our luggage despite being told differently. Flight itself was great. Charges were unfair.

We were charged a ridiculous amount for a name spelling error on ticket which I would’ve corrected if I received pre-check info more than 1/2hr before flight. Then we were told at ticket counter that our bags were fine for boarding but then we’re charged another ridiculous amount to take in our luggage despite being told differently. Flight itself was great. Charges were unfair.

Apart from an email about re configuring passenger seating less than 24hrs before flying it was all good.

There were a lot (4 I think) of EasyJet flights leaving Agadir, we arrived two and a half ours before our flight. Very slow to get through the booking in, passport control and security!! We had booked in on line but had to Queue with others who had not to drop our bags off!,

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?

I was hesitant to book with a low cost airline due to previous experience but Easy Jet surpassed my expectations. I would definitely book a flight with them again! Seemless booking, upfront about baggage fees, professional, and helpful staff.

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

Usual issues with flight delay. Perennial problem of travel by plane.

i didnt go this was a hacker booked this flight on my debit card !

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

Small plane, only two bathrooms, no screen for videos. Not wide enough seats

The flight was delayed by an hour. Made the connection uncomfortably tight.

Complete mess. Our reservation was mistakenly cancelled. After almost missing the connection and walking all over the Munich airport, the Service desk got involved and we were run to our flight. Not all 4 of us in Business and not seated together as originally booked. This was the worst treatment I have ever had. And I travel a lot. 1K million miler.

Upon arriving at IAH, it was informed that the luggage had not arrived. Still waiting to hear back when it will be delivered.

The aircraft was old, there was no charging sockets, and the seats were narrow and uncomfortable even though I had exit row premium seats.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

The flight was delayed and I was stressing the whole time about whether I would make my next flight.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

Flight was okay however bags were left in London even though we had a 7 hour layover. Bags are yet to be confirmed to reach final destination. Horrible work.

Quiet and comfortable aircraft, pretty smooth flight. Very comfortable business class cabin with decent entertainment. Good service from the crew. All in all a good experience.

Very quiet aircraft, business class was spacious and comfortable. Very pleased with the service.

Why does a reputable airline like BA allow a miserable domestic airline like AA to operate its flights? There is no comparison between the two

When i booked my flight, my ticket shows that i have 2 pieces of luggage allowance. Once i got into the check in, i was informed that i needed to pay extra for my two suitcases, and was put into a very precarious situation, I had to pay close to £200 for my two suitcases and these were not extra burgages, I felt extremely disappointed. In case i never had the kind of money, it meant that i would have missed my flight

Boarding is a mess. They never check group # so lots of people crowding in. Comfortable seats this flight. I had an empty seat next to me, very convenient. Food was really not good, but I was starved. The pizza snack thing was horrible. Crew was grand. They really make it enjoyable.

Crew very helpful and friendly. Food is so so. Main meal is not always the best. Did have a choice of a snack part way which was either a cookie, corn snack, or similar. Second kind of meal was basically like a pizza pastry that really wasn’t a favorite but probably a European snack? Screens and selections of movies, tv and such were good. No WI-Fi unless you buy so no free texting or such on the long flight but I think that might be any overseas flight.

LCY airport is an amazing airport and I love the flight from LCY to FRA with BA. Efficient, easy, comfortable and great luggage allownace with BA. I iused to fly predominantley LH, but the service and price - benefit ratio of Lufthansa has deteriorated a lot over the last 5 years. Whereas BA keeps an excellent service level with friendly staff.

Flight Attendant Karen Lynn was an absolute delight. She assisted in every portion of the services provided throughout the flight, aided with any and all concerns expressed by passengers, and even helped comfort an upset child who was one of five of a traveling family. This quality of service is what keeps me coming back to American. Thank you!

The airplane was old. Some things didn’t work out of middle seat was broken. The rest was OK.
