Cons: "I asked the Chinese flight attendant in economy to please ask the man in front of me to put his seat up since the captain and purser had already asked us to do so in three languages The man in front of me refused to do so. She said she was going to start at the front of the plane and let him leave his seat back making it difficult to see my tv monitor. I thought that she should’ve said that it was time to put your seat up. It was frustrating that she didn’t support me and the request of the captain. Your seats are very uncomfortable upright when the person in front of you has their seat back."

Even then she was not satisfied, she abused me the whole flight damaged the screen so I could not use it until the steward fixed it. Demanded that I except any and all alcohol to give to her to drink. When I am tea total she then continued to abuse me.

Cons: "After 2 hour delay, the flight was cancelled. NO ONE helped to find another flight. After waiting in line for 2 hours, the ticket agent handed me a card and said I had to call the 800 number. The person on the phone said I had to talk to ticket agent to go standby on a flight to Munich and the ticket agent told me I had to call. I was caught in a loop and no one helped. Then when it became apparent I wasn't getting out that night I was informed that there were no hotel vouchers and I would have to find my own hotel! After searching for an hour for a hotel (all were sold out in Boston) I called a friend who lives outside of Boston. No one gave me a taxi voucher because it was not to a hotel. LUFTHANSA customer service is the WORST!!!!!!!!"

Cons: "Passport control in Frankfurt was slow, very long linen under staffed"
Pros: "The staff was friendly and professional"
Cons: "The seats were too cramped, no chance to sleep on an overnight flight. In fact my back was quite sore from being cramped in the seat with no leg room and no under seat room for a small backpack. I’m only 5’2”"
Pros: "The cabin crew was very friendly and professional. The food was good too. The flight was right on time."
Cons: "Very little leg room, when perso in front of you reclines it’s impossible to open table"

I wasn’t able to check in online the day before or the day of because their web configuration or business model idk. I arrived an hour early and check was closed and there was no one around to speak to and eventually was told there was no possible way to get a digital ticket despite I had no luggage to check and would have easily made it through security to boarding and had to pay for a new ticket for $330 ontop of the $169 I spend for the ticket and then I missed my rental car for $305 because I only arrived at midnight instead of noon that I was originally intended. All booked through kayak. I hope there is some kind of insurance from kayak because this was totally preventable had I not been blocked by play air from getting my check in and plane ticket.

The staff was very professional, the places very clean. The legroom was a little bit tight but so worth the price of the flight. Very pleased! Next time, I want to book a stayover to explore Iceland :)

The boarding process was easy, the crew was friendly and the flight was very smooth. There is a limited menu the food was tasty, but you have to purchase everything. The cost of the flight was very reasonable but everything such as baggage is extra.

Play is a great budget airline. There are no TVs or chargers in the seat but there was more legroom than expected. Boarding and all staff that I interacted with were great. You have to pay for any and all drinks or snacks you might want on flight.

Play is a great budget airline. There’s more legroom than expected, no TVs or chargers in the seat, all staff that I interacted with were great.

Blood sucker budgeted airline. Charging after and after. No one should busy air ticket in this airline. Completely a scam and sucking blood.

The cabin crew very kindly arranged a change of seats for us due to a distressed passenger

There was no food or entertainment. That was fine, not a problem. I paid for “priority boarding” ( and a cabin bag) but there was no “priority boarding.” That was disappointing and falsely advertised so perhaps that could be adjusted.

No frills airline. Excellent service. Very good leg room for passengers compared to other "full service" airlines. Crew was very friendly. No entertainment system other than flight information display which was surprising as I thought it would be another revenue stream for them. Overall a surprisingly excellent experience.

Great new carrier to Europe. Lots of leg space and friendly crew
