I had to put up with *loud* banter from 2 flight attendants at the back of the plane throughout the entire flight, which was freakin' annoying to say the least. I'm NOT interested which pilot or male attendant you find cute or want to make out with. You also really shouldn't laugh at passengers' faces after telling them to resume their seat to the upright position. A real shame since their performance "on the floor" was perfect.

Landed in Canada to let off a "sick" passenger, sat there for hours and after the pilot made countless excuses, including needing to refuel, needing a new route, and needing to de-ice the plane, he finally announced that we're headed all the way back to Newark for some unknown reason. Worst flight ever. Couldn't be any less happy. F*** this airline. Will never use again. Ruined my vacation, thanks a lot.

I wish service could be a bit faster. Due to turbulence our second meal could not be served at all. Not sure why the passengers were not served as they were seated.

Alitalia gets a bad rap, but I thought this flight was excellent, and a comfortably way to travel the 13 hour flight from Rome to Los Angeles. Cabins recently refurbished on 777 thanks to Etihad Airways investment. Food, and plenty of it, was excellent. Wide selection of wines. Choice between freshly made American coffee or Espresso (from Lavazza). Lie flat seats are way more comfortable than KLM. Esoteric selection of documentaries and Italian movies. Leather seats and color scheme is elegant. Also, business class lounge (Alitalia House) at Rome Fiumincino serves delicious freshly cut Italian cold cuts, cheeses, pastrries, and has an actual barista vs a machine. You don't get the sense that they are cutting corners, which is probably why the airline keeps losing money, but that is to the benefit of the traveler (for now). Service friendly. For nonstop to this part of Europe, or for connections to Southern Europe, it may be my number one Skyteam choice.

Check in is extremely unorganized and long lines at Sky Priority, but someone finally directed me to the VIP check in in the back, which you can use if you are flying Business Class or have Elite status. This was not indicated anywhere, though, so make sure you ask or look for it if there is a long line at check in. Then, the gate is very, very far. Not sure why they had me check in at Terminal 1 as the gate is in Terminal 3. Make sure to allow for plenty of time, and maybe see if it's possible to check in at Terminal 3, which may well save time. But for a 14-hour flight in total comfort, the trade off was worth it.

We arrived at the airport at 9:00 to check in for our flight that was scheduled for departure at 12:15 and we were told that we could not check in until 2 hours before the flight (10:15). All of the passengers for flight AZ1466 lined up in front of a check-in counter that displayed Alitalia for our flight. At 10:45 they announced the check in for AZ1466 at a different check-in counter knowing full-well that everyone was lined up for flight AZ1466 on our line. So then everyone that was lined up at the first counter had to line up at the new counter. My wife and I were initially 3rd in line and then after we had to move we were in the very back of the line. On top of that, they only had 1 person checking everyone into economy (which was most of the people on the plane) and they also had to weigh everyone’s carry-on baggage. We were initially told they had weather issues with the snow in Rome and they did not know if we would take off on time or would be cancelled. However, I was getting e-mail messages from Kayak stating our flight was on-time. So how is it that a 3rd party travel company knew what was going on, but the crew at Alitalia did not? Afterward I had to go through security, wait on the tax refund line, and go straight to board the plane. After that we waiting on the plane for 50 minutes and did not take-off until 1:05 PM. These were the problems in short: 1.No one informed us that we could not check in at this particular airport until 2 hours prior to flight departure. 2.They did not begin the check in process until 90 minutes prior to departure. 3.We had to switch check-in lines and they only had 1 check-in person. 4.We had no time to shop or eat lunch at the airport. 5.We boarded the plane and waited until 13:05 to takeoff when we were scheduled to take off at 12:15 (50 minute delay). 6.We received no communications about delays from Alitalia (via e-mail or app). However, we received e-mails from Kayak stating everything was on time. We had no communication from Alitalia about the delay or that we could not check in early (which you could do at every other airport I have been to). We also had a connecting flight in Rome that we were concerned we would miss. We arrived at Rome airport on a delayed flight out of Marco Polo airport (AZ1466). Our 13:40 flight to JFK (AZ610) was delayed until 14:45. After we arrived at Rome airport we ran through the airport to our gate and boarded the plane. After we boarded the plane we waited until 16:10 to take-off (85 minute delay). We did not receive any communication from Alitalia via e-mail, the Alitalia app, or crew members that our flight was being delayed any longer than it already was. We planned on stopping to use the bathrooms in the airport, eat a decent lunch, and shop (which I promised my wife we could do at the airport). However, we could not do any of those things because we did not receive any information about delays from Alitalia. After we arrived home in New York the airline l

All the food were terribly salty, inedible because the beef was hard like rock, I was unable to eat or chew. The sauce was salty and terrible so threw them away. In general, the food were inedible and poorly prepared that means they were not considerate and discreet about cooking, selecting material,too. The airline only pick the terribly cheap meat to scam and mistreat the passengers. I felt I was ripped off and sadden.

Flight ETD was 8:25 but plane developed a mechanical problem. After about 20 minutes waiting for maintenance the Captain decided to go back to the gate for fuel and repairs. After maintenance came on board the decision was made to deplane. Finally, a plane from Chicago was scheduled to take us to San Diego. After boarding at about 12:30, it was discovered that catering never loaded food. We waited for over an hour for food to be delivered. At close to 2pm the Captain, who kept us aware of what was going on, asked us if we would agree to leave without a full delivery of food, and all agreed. So by 2pm we were finally enroute to San Diego but having a seat in the back meant we only got to eat what was left, which for me, was a small cheese pack.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
