KAYAK’s top tips for finding a cheap flight from San Francisco to Cagliari

  • The main departure airport for flights from San Francisco to Cagliari is San Francisco International Airport (SFO). However, a few flights from San Francisco depart from Oakland International Airport (OAK) and San Jose Mineta International Airport (SJC). The advantage of departing from SJC or OAK, which have less popular routes, is that you have a better chance of finding lower ticket prices.
  • Since SFO is the fifth largest United Airline’s hub, booking this airline for your flight to Cagliari provides several advantages. Among these advantages is the ability to book a flight at any time of day that is convenient for your schedule. This is due to United Airlines' many daily flights from SFO to Cagliari Elmas Airport (CAG), which serves as the sole destination airport for flights from San Francisco to Cagliari.
  • When flying with your pet(s) from San Francisco to Cagliari, book Alaska Airlines. Although all airlines on this route offer pet-friendly policies, Alaska Airlines stands out due to their lowest pet fees. Furthermore, Alaska Airlines allows pets to travel in-cabin, as long as the total weight of the pet and carrier does not exceed 20 lbs. The animals must also be at least eight weeks old.
  • If you plan flights that stop at one or two points along the way, you will most likely pay less than if you book direct tickets from San Francisco to Cagliari. Air France, TAP Air Portugal, and SWISS are among the airlines that provide layover flights. The three most typical layover airports for flights from San Francisco to Cagliari are Humberto Delgado Airport (LIS), Amsterdam Airport Schiphol (AMS), and Frankfurt Airport (FRA).
  • After landing at Cagliari Elmas Airport (CAG), use the cost-effective bus line 160 to the city center or other places inside the city. The bus ride from the airport to Cagliari takes about 20 minutes.

The food was good. Most the staff was pleasant. The flight would be drastically improved with WiFi on a long international flight.

The food was good. Most the staff was pleasant. The flight would be drastically improved with WiFi on a long international flight.

When I needed to get my bag off of the plane so that I could take a train because the connection was 4 hours later, they took 2 hours to take my bag off making me take the train and miss my flight simultaneously. The seat size on the plane is too small for an average aged woman let alone a middle-aged man. It's unacceptable and I will not fly Boeing again.

The flight was generally good but was delayed departure meant a very late arrival for a connecting flight.

They didn't give us Nothing to eat, come on..... 1 package of chips and a glass of soda won't do anything to the company

The cushion of the seats are old and very thin. The food can be more tasty or come with salt packages

The biggest let down was with booking experience through Kayak. I booked a flight with checked bags on Kayak. Right away I got a message from travel agency that the flight is not confirmed and to call them. I called them and they said the flight I have booked is no longer available with the price I have booked it for and I can book it with about $100 more. I already had other options I could book with cheaper price so I asked them to cancel my booking. Then they said I can have the ticket with the same price but a date change which was not working for me as I had to be there for a seminar. So again I said no then they said they will cover the charges and confirm my flight. When comes time for check-in I see I have no checked bag option which means the travel agency deceived me saying I can have my booking as I had booked it. And at that point I ended up paying $155 for my checked bag going back and forth. I am extremely angry and unhappy with this experience

PLEASE DONT TAKE FORCEFULLY(SIZE APPROPRIATE) CARRY ONS FROM PASSENGERS WHO FOR SOME REASON NEED TO KEEP IT

It was great. My seat was comfortable. The bathrooms were clean . The service was superb . I travel a lot and I have been in 64 counties. I wish I could fly first class, even though I could , but I prefer to budget my yearly travelling expense on actual visiting , not on flight. Anyway, my point is that your economy was far much better than other airlines as good as Air France. The flight attendants and all crew were polite and very helpful and respectful. Thank you for making my long trip tolerable.

I slept the whole flight so I can't tell you about the food and there was no entertainment offered. Crew was very nice, seats were comfortable in business, and boarding was easy.

The service was flawless. The trip went great. I flew from Venice, Italy to Tampa, Florida. The issue is my bag (that I checked for free when checking into the flight) was ripped along the side when I collected it from baggage claim in Tampa, last night. I thought of talking with the Tampa baggage claim employees about it and see what could be done, but my bag isn’t a very expensive bag and I didn’t want to make a big deal of it. I’m not sure if I’ll be checking a bag anymore in the future.
