the seats were bad and uncomfortable and the food was not tasty.

the seats were so cramped you could barely move. it was difficult to eat when passengers would recline their seats. the seats were so flimsy and unstable that whenever someone got in and out of their seat, it bounced like a spring back in your face. the movies were nice. the food was terrible. even though the conditions were terrible, they tried to pressure passengers to relocate their seats to accommodate adults who were related and wanted to sit next to each other, even after the passengers expressed that they did not want to move for that purpose. on the connecting flight, the “service” consisted of items for purchase. even though the flight was only 45 minutes, once again passengers (including me) were pressured to relocate for people to sit next to each other. they couldn’t be apart for 45 minutes? this was much less compelling than being apart for an 8 hour flight.

Everything went smoothly, and we even arrived 40min earlier than scheduled, on an Orland-Madrid route.

It was budget airline Veuling, even though we booked Iberia.

The staff was very nice and helpful. Some of the best crew I have met.

Bad experience. The seat room are very tight. The food is not good and the breakfast has no hot drink.

Suddenly, I don't find my flight back on the app Help Ticket 0757345716866 Hoeflich Flight back Sunday ib5333 Ib2629 Ib4268

Great : The crew was awesome ♥️ To improve : - The rice in the "Rice with chicken" was rather s kind of rice pudding, not good at all - No power outlet to charge your phone. 😒

It was a good flight overall. Nothing to add. Keep it up!

Excellent. Thanks to United Star Alliance, since economy was overbooked, I’m grateful to have been upgraded to Business Class.
