My son was served a muffin which had broken pieces of glass in it. Thank god he didnt swallow them and spit them out. i did let the crew member know and took pictures but nothing they could do. This could have been a very dangerous situation.

My son was served a muffin which had broken pieces of glass in it. Thank god he didnt swallow them and spit them out. i did let the crew member know and took pictures but nothing they could do. This could have been a very dangerous situation.

Sitting at Logan on the taxiway for 90 mins waiting for a gate after an 8 hour flight is unacceptable. Logan and delta need to do better

The flight was long and offered very little comfort. The seats were exceptionally small and quite uncomfortable, making it difficult to rest on a long journey. The onboard meals were below expectations, although the cabin crew was excellent throughout the flight—professional, attentive, and courteous. I understand the commercial pressures airlines face, but maximizing capacity by reducing seat size and comfort has become an industry-wide concern. While many travelers will continue to tolerate these conditions out of necessity, an increasing number of passengers will choose alternative airlines whenever possible in search of a more comfortable travel experience. Investing in passenger comfort is not only appreciated—it is also an important factor in long-term customer loyalty.

There wasn't a time for neither food morning entertainment in a short one hour hop over.

Boarding in Rome for the Venice connection was disappointing. Very hot after a long flight, being herded on a crowded, unairconditioned bus to be transported to the tarmac for boarding for our connection. ITA you can do better than this, especially for international passengers!

This was a typical hour-long flight. Not much leg room, no entertainment and no food.

The boarding was delayed and they didn’t let us know why until after we sat on the plane (the plane was delayed getting in) but they had us waiting in line for over 1/2 hour for some reason which I didn’t understand.

A lot of things could have been better. They lost our luggage. We missed our connection from YVR to Naples when we arrived in Zurich and then we got re-routed to Rome and then Naples. We eventually got to Naples but our bags didn’t. Our experience at the lost luggage in the Naples was not at all reassuring. They didn’t seem that interested in our problem. I did a live chat with Swiss customer service and all they could do is tell me to follow the process. Meanwhile we’ve had to spend significant money on clothes and I have to replace medications. This has meant our trip so far has been totally different than what we had planned. It’s not clear that our baggage will ever show up which means we will have lost significant amount of clothing and other things and our two month trip to Europe will have more problems than good memories. So far we are not happy.

Terrible service, uninterested employees, inefficient boarding process, and marginal set up on plane. Staff make the airline - good luck with this one.

Long delay, lack of space at the seats (not comfortable).
