The flight was delayed twice. When the crew explained about the debris causing flat tires, I was glad they took the time to change all four.

The flight was delayed twice. When the crew explained about the debris causing flat tires, I was glad they took the time to change all four.

Great to have power available for every seat in Premium Economy. I do wish the WiFi was less expensive. It was 23-24 Euros for the flight for one device. And there were times it was unavailable.

Very good service from San Jose to Madrid . Ryanair service from Madrid to Brussels 😕

I paid to upgrade to Business Class. The queue to check in at the Business Class aisle was full of people without Business Class tickets, the fast-track immigration line was “closed” but the representative opened it up for his friends, regardless (there was a lot of fist-bumping), and the lounge was an absolute mess…..4 staff sitting playing with their phones while every table had dirty plates and glasses waiting to be cleared…..and the least said about the rude lady on the reception desk at the lounge , the better!

online check-in was horrible and didn't work either way

The airline refused to board me because I showed up only 50 minutes prior to departure time, despite the fact that shortly before that, when I arrived at the airport still in time, they changed the terminal and I had to take a bus that took 20 minutes. Keep in mind that for some maintenance error I could not check in online like I usually do. Personnel at the airport was unable to let me in, customer care was beyond useless, the original airline operator (Iberia) was as useless as a toilet paper roll core in time of a wipe and all this uselessness made me waste my ticket, my reservations, my long time parking, food and most of all the joy of being with my family for the new year after working my bottom off even at Christmas. Am I happy? Come and ask me in person!

Its a bus taking you on and off the plane so if you have big luggage … more muscles needed

Great food, excellent service. Did not manage to make wifi work but in a flight of less than an hour it was not a big deal

When having a connection at Madrid, it’s extremely confusing. You must travel from your arrival gate, all the way down stairs to a security check point, go up stairs, then downstairs to another security check. Then make your way to your gate. All the while traveling through a “mall” inside the airport which makes it difficult. 10/10 don’t recommend connecting flights through Madrid.

okay, will recommend from PR to Madrid, faster turn around

The plane delay due to a poor judgement of the pilot. It was the only flight that got delay due to fog.

Service was bad and food they told us they only had pasta very rude

The media system is so inreliable, it keeps freezing and restarting at the begonning. Old planes with an old entertainment system makes a long flight very boring

Entertainment system is old, touch screen isn’t working properly. New movies should be added atleast once a month Should provide toothbrush and toothpaste at least when asked.

The boarding system was all bogus - employees at the boarding gate were not sound like proffesional or may be possibly rational

I got an email in the morning of the flight 1/7, from Kayak, that I was rebooked from UA 906 to LH 430. Nobody at Lufthansa ot United knew about this. I went to both counters. at the airport. Also, Cheap Flights, who I booked the ticket through, did not know. I ended up staying on the United flight. But this was very disturbing, since I got a very late notice that I was rebooked to an earlier flight, I hurried to the airport to find out after a lot of inquiring that this was a mistake. Not a good Kayak experience.

Using the media screen in economy class is a disaster

I requested a wheelchair for they haven’t got it, they are old and don’t speech english

Pretty standard. Crew was helpful and friendly. Plane was clean and food was good.

The plane was late and had not been cleaned prior to our flight from Frankfurt to LA, so we had to use bathrooms that were completely filthy and stank like hell. One of them eventually was even closed early on during the flight. It was a horrific experience.
