Airline reviews

I’ve never heard of discover airlines but will definitely be on the lookout for future flights. Everything about the trip was perfect. The staff were exceedingly friendly and helpful. The only critique; there was a delay and gate change and this fact was NOT well published! My eTicket was NEVER updated with the new flight details. We ran the whole way from our connecting flight only to find that our flight was delayed. Very frustrating. Additionally, there was NO announcement regarding the root cause of the delay. The uncertainty about the cause of the delay contributes to the overall frustration. One other small matter onboard; one of the toilets was unavailable (or perhaps malfunctioning) and NO explanation was given nor was any workaround explained. It would have been less frustrating if they announced why the toilet was lock and explained the alternatives in detail. That way the foot traffic congestion could have been minimized.

Basically a low cost airline, with very small seats, mediocre food and staff not particularly nice. Not a pleasant flight

Plane was old and small. Crew was not very friendly and didn’t check in much or offer water more than 2 times over a 8 hour flight.

We were on a full-service fare as part of a long-haul trip so it was disappointing to be on such a no-frills flight (no meals/hot drinks/entertainment) especially for a 3.5hr flight, at the start of a long trip. The crew however we’re lovely & friendly.

Business class seats were harder than expected, and lie flat we're not very comfortable. Less expensive than other business class flights, and much better than flying economy. The crew was excellent, as was the food.

Boarding was slow and getting off the plane took a long time. The crew did not have enough water for the trip.

Boarding was a bit chaotic, planes were on the oldish side. Otherwise, very nice flight. Would fly them again.

food was terrible on the plane, bring your own food, its not worth eating.

Turkey slices for breakfast. What happened to eggs, bacon, and sausage? The TV shows could’ve been more comprehensive as well as the movies.

The plane was small and one felt the turbulence much more. The lines to get through immigration were insanely long.

Our steward Margarida who served us from Lisbon to Boston was absolutely fantastic! She deserves a raise. Conscientious and thorough as well as showing appropriate attention for every need.

Comfortable but not Polaris or Delta comfort Business Class. Overall 7 out of 10

A bit disappointing. Our business class seats were not cleaned from previous flight. They were also missing headphones and bottled water. Dining options were not always available.

I have been flying internationally for most of like. My first trip with TAP- wonderful! I look forward to flying with them more frequently in the future!

All went smoothly. Got assisted travel which was easily arranged and delivered.

Smooth journey made good time. The aircraft was littered and did not look very presentable.

On time departure; arrived early into Faro. Air Malta operating flight, crew friendly and efficient.

Food and entertainment were not available, so my rating on those items isn't actually correct. There should be a "Not relevant" or "Didn't use it" option.

I didn't know that all connecting flights require online check-in two hours in advance, so I was fined 55 euros. This is a lesson learned.

There isn’t any entertainment. The food and drink was available for a price. I didn’t buy any.

It would be nice to have power to charge phone.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

50 minute of delay on a flight scheduled after 22pm is really annoying. This was even the only flight departing from Frankfurt Hahn on that evening so the delay was inexcusable

Unfortunately didn't realise how far away Frankfurt Hahn airport is from Frankfurt the city. Outbound flight was delayed by 2.5 hours and no communication at airport, just a whisper emknating through the packed crowd ready to board at the gate as someone read out an email they had received. All rather poor and pathetic

Proximity of the the gate to the lounge could have been better but overall a nice experience. The lounge was exceptional. Getting from the Schengen side to the international side was also pain free. Boarding the plane, service on board , disembarking at Heathrow and quick delivery of bags all made for a good overall experience.

Again another extremely chaotic boarding for the flight. Could have easily opened up more automated gates and the staff could have proactively managed the queues as they're forming rather than sitting behind the counter, waiting for the boarding to start.

My flight to Frankfurt was a very pleasant experience. The food was good, but what really stood out was the cabin crew, who were exceptionally friendly, attentive, and professional. The service was excellent—honestly, better than on some much more expensive flights I’ve taken. A wonderful experience overall!

The flight from FRA to SFO was uncomfortable. The crew allowed people to change seats after boarding finished, but then made some people move back to their seats but not others, which resulted in my wife and I having to sit in two middle seats for an 11 hour flight. The entertainment system was not working well throughout the flight, and stopped working completely around hour 8.

Review what was entered already in the same booking. Not sure we will use Arrant Grant, given what happened!

Great service food was very good and overall experience was great !!

When I fl with Bulgarian air, I am greeted with a bottle of water and a packaged cleaning wipe. There is a hot sandwich and a drink offered afterwards. Towards the end of the flight, there is a piece of chocolate and per request an additional water bottle. For the price that Lufthansa charges per ticket, it is embarassing that other airlines can offer better customer service quality on board. Also, some of the Lufthansa flight attendants act very entitled instead of being customer focused. Regularly the mobile lift for diabled passengers is missing... Every time when I fly with my 89 year old mother, she is being questioned multiple times whether it is okay to use the stairs ( she walks with two canes). Most of the times when we arrive in Frankfurt, the mobile lift is missing and she is urged to use the staircase. When I refuse to allow this, the flightattendants look at me scornfully. This is not WW2 where disabled people should be treated as second hand people... Then we all have to wait another 30 to 40 minutes on the airplane, while waiting for the mobile lift to arrrive. Does Lufthansa have enough money to waste on an airplane waiting for (on the average) 30 min for the mobile lift to come? I fly frequently and have experience mostly with Delta, United, Southwest and other American Airlines. Lufthansa needs to pick up their game on board, if they want to stay competitive and in the game...

Very bad 3 times change the gate and too much delay...

Poor communication from airline, didn't start boarding until 15 minutes after we were supposed to be in the air and there was no communication from anyone about a delay except the screens showing we were "on-time" and already "boarding" which finally updated 5 minutes after we were supposed to be in the air to "delayed".

Prompt boarding, safe landing and they didn't lose our luggage. No entertainment and no USB plugs to charge phones. No food, though I might have been asleep.

I ended up upgrading to business class. They use Seat Boost and even though I was the highest bidder at 900 Euros, they decline my offer. When I got to the Gate, I asked if I could upgrade and they said yest for 1300 Euros.

The flight was 1 hour late due to technical problems with the plane. We paid for premium economy seats, but the seats were extremely uncomfortable and just as crowded as regular economy seats with perhaps a little more legroom. I had to pay extra to select our seats in advance. Compared to other airlines with premium economy seats, Condor’s premium economy seats were poor and other airlines don’t charge to select your seats in advance. The worst though was the toilets. They ran out of toilet paper with 4 hours left in a 12 hour flight, trash was overflowing, and the toilets were smelly. I will never fly Condor again and I will advise my friends and colleagues to never fly Condor.

Terrible. I can't believe I lost my entire ticket price when I tried to cancel or change the flight the day before.

Excellent airline. New planes. Comfortable business class seats. Professional crew

Frankfurt to San Francisco The Site would not let me Upgrade luggage ( paid extra at the airport Had to pay for seats but did not receive those seats Had to pay extra to check in at counter (since I could not upgrade on the app) $25 a person. Unfriendly staff- bordering on rude Check in in San Francisco (to Frankfurt) was smooth, courteous and no extra charges for seats or check in

It was a short flight, maybe an hour long. Everything was handled great.

Missed this flight. $5000 to rebook next day. Horribly rude staff in Frankfurt. Everyone we encountered was either not helpful or outright mean.

Condor's computers do not work. They do not leave enough time to catch a connecting flight. Condor had to book passengers on a different airline to make their destination. They lost my niece and nephew's luggage. The bathroom had pee all over it before the flight took off.

Awful!! We got stuck in the passport line for two hours. Condor acknowledges that the lines are really long but says it is not their problem and would only rebook us in two days. We are stuck in Frankfurt for two days and it cost us $500. Condor stated that they gave us a 1.5 hour layover which was more than enough time and in the next sentence said, yes we know the lines are a problem.

I used Kayak.com to buy plane tickets, which sent me to Underpricer. Immediately upon buying the tickets I started getting phone calls telling me that my "tickets were not guaranteed" unless I paid more money. I told them that if they've sold me on just the idea of a ticket, and not an actual ticket, then refund my money immediately. We argued, but they eventually said they would do that. They didn't, I refused the charge on my CC, the CC company eventually charged me anyway, and Underpricer still didn't cancel that ticket because I kept getting alerts to get on that flight. In complaining to Underpricer, they insist that it's my fault and that the most they can do is refund the fees. This company is using deceptive practices and harassing people, and the company needs to be banned from Kayak and from doing business in the US.
