Icelandair $263 SFO to London round trip Oct-Dec

Icelandair has unprecedented low fares for San Francisco to London LHR starting at $263 round trip. These ticket prices are available through Priceline. The same itinerary on Orbitz prices as $343 and I was unable to pull up $263 Momondo ticket prices. The catch is this an economy light low fare with carry-on only free bag allowance. Also, the lowest fares force an overnight in Iceland on the return flights. Add $100 to the round trip ticket price if you need a checked bag.

Icelandair website has $335 round trip tickets without an overnight layover in Iceland.

This sale made me a buyer today since I can get a round trip ticket from London to Sibiu, Romania for $120. I missed out on the spring trip to Romania I had planned, so this is my next opportunity for Romania.

Update 5-20 9:40am Pacific: Priceline sent my Icelandair record locator number. I logged into Icelandair and selected seat assignments for all four flights free of charge and entered my frequent flyer number and passport information. All good to go for a $270 round trip to London and Iceland in the fall.

    To which FFP are you crediting? I booked early December with a 2-night stop in KEF on the return. The simple roundtrip fares I looked at on ITA says these are P fare class, which earn nothing at JetBlue, and aren’t on Alaska’s partner chart.

    @GeeEmm – Finnair earns 50% on P fares.


    Finnair also earns 100% on American Airlines cheap O fares. I have been seeing lots of low fare tickets to Europe with AA too in O class.
