Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

The service was fabulous and the food was excellent. My luggage was left in Frankfurt due to late arrival but it is supposed to arriving on tonight’s flight.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

As expected. Would have appreciated a 3-day headsup reminder as a reassurance that all is well.

The plane was late (as was my flight out from Birmingham the day before)

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

When I booked the flight with Cheap Flights I actually booked in Business Class. When I got the confirmation it showed that my flights had been purchased by Cheap Flights in Economy Class with an Upgrade to Business Class. At first I was surprised and then the problems started. If you are not a seasoned Traveller you would not have been able to handle the issues this created. 1: the lay over time for the connecting flight in Frankfurt was 45min, which is extremely short and even the slightest dealy would have resulted in me missing the next flight. 2: the checked baggage allowance in Buisness class is 2 bags/ ea, 32Kg., however, my ticket being booked in Economy with an upgrade to Business only allowed for 1 bag/ 23 Kg. when I did the online check in my Boarding Pass showed a checked in Luggage allowance of 1 bag/ 32 Kg. which was very confusing. I called the Airline and asked what my checked in Luggage allowance actually is and was told 1 bag/ 23Kg. Since I have a frequent Flyer Status with the airline my baggage allowance increased by 1 bag / 23Kg. When I arrived at the airport I asked to be booked on an earlier flight, in order to avoid the stress and possible missed connection and I was lucky that this was possible. If this had not been possible, I would have missed my connection due to weather and even I am not quite sure, if and what the consequences of my cheap ticket would have been. My point being: if all of the above would have happened to an unsuspecting/unseasoned traveller, this trip would have ended in a disaster. The issue with the pricing is that the alledged money my airline received and what I actually paid to Cheap Flights shows a $1,000 difference. In conclusion, I would stay away from Cheap Flights if you want a hassle free experience!

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.

I flew four flights on British Airways within two weeks. I was unable to download the boarding pass to my phone for any of the four flights. I could check-in for my flight but the system would not give me boarding pass. I tried multiple ways and multiple times. I discovered many other passengers also had the same issue with their boarding passes. No explanation or acknowledgement by BA.

The plane was a long way from departure lounge. The plane looked tired but got us there.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Because our ABZ-LHR flight was cancelled by BA for reasons they refuse to tell us--not weather--we did not make this flight and were booked on the following day. BA offered no assistance to us on the phone or in the airport, and we had to find a hotel at Heathrow on our own.

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Poor service, antiquated plane with 2-3-2. B-class config upstairs. Tight and not comfortable—not what I expected for paying B-class! AND my bag didn’t make the transfer, bag will be delivered the day after it lands!

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

Business class lounge for my gate was closed and no email was sent, causing me to walk back and forth to different gates, etc for over 20 minutes one way. Flight entertainment was mediocre with very poor choices especially for business class cabin. Original flight was cancelled and rebooking was difficult and no reason given for cancellation.

Very comfortable flight and simple and directed one way and back. Amazing price.
