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.

Very nice crew and great food. Easy to board just wish the flight could be shorter or seats more comfortable or more room to walk around when you get cramps in your legs from sitting so long. Crew was great and attentive and really was good food.

Very nice crew and great food. Easy to board just wish the flight could be shorter or seats more comfortable or more room to walk around when you get cramps in your legs from sitting so long. Crew was great and attentive and really was good food.

Terrible - we needed tp change the flight and it was impossible. They ask for a price that was higher than buying a new tickets from another airline. Will never flight Swiss air and Luftgansa again.

Food used to be better and comfort was not attainable after 5 hours everything starts hurting.

horrible.. they cause such a problem and my daughter 14 years old was stranded in san francisco

I can’t even the whole trip was a catastrophe

Poor. Seats uncomfortable. No leg room. Hot and humid the whole trip. Food and staffs were ok.

The seats were so close together, when the man in front of me put his seat back, the screen in front of me was 9 inches from my face. There is no way to lean forward if I needed to pick something up. It was pretty uncomfortable for a ten hour flight. I was very surprised.

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.

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
