Lowest International Flight BookingThe lowest international flight booking
Well, first you have the basics: -Start the flight hunt at least 6 month in advance. Get the flight information. Don't necessarily make your booking so early, but some carriers will publish it later. However, if I fly international, I can get lower rates, with fewer departures from San Francisco (SFO). Regularly review pricing on all important rice locators.
Kayak, Expedia, Orbitz, CheapOAir, SkyScanner, Google Flights, Vayama etc. And the more you look for, the better. Set a flight alarm (I like the ones on kayak and skyscanner) to send you an e-mail or SMS when the rate drops. If you want even better offers now, you need to be ready to be flexible: - If you don't care to go to other dates:
Place in the data area of the data you are ready to travel, and let them find the best rates for you. If you don't mind making a pile of stopovers: Look for flight to towns in the same region. Some of the least expensive flight options are from San Francisco to Europe, Dublin or Moscow.
So, if I wanted to go to London, perhaps it would be less expensive to look for SF to Dublin and then Dublin to London flight to London later. To find the best price town in the area, use Google's "Explore Map" flightfinder. But the only trouble is that you may have to pass duty in the countries where you are, as your two tickets would not be on the same one.
If you don't mind going on cheap flights: Fly with Norwegian, WOW and Icelandair.Pros: Pricing can be as low as $200-$300 US to Europe round trip. Even if you don't want to travel to Iceland, Norway or Sweden (Norwegian has some London flights), you will probably need to change your flight to your endpoint.
