Airfare deals are typically only available on limited dates. We recommend you use Google Flights to find dates to fly, then book through an online travel agency such as Orbitz or Expedia, which allows you to cancel flights without penalty by 11pm Eastern Time within one day of booking. However, if you’re using The Platinum Card® from American Express, you’ll need to book directly with the airline or through the Amex Travel portal to get 5x MR points (on up to $500,000 on these purchases per calendar year). Remember: Fares may disappear quickly, so book right away and take advantage of Orbitz or Expedia’s courtesy cancellation if you’re unable to get the time away from work or family.

It looks like a bit of a fare war is happening on the West Coast.

It’s a great opportunity for folks who can make California to London work.

When you go to book the flights, they send you to Smart Fares which suggests they are regular economy fares, but I’m not convinced they don’t book into basic buckets. showing cheap flights from SFO to LHR. showing cheap flights from SFO to LHR.


I was able to find fares for $390 on many dates in May on American Airlines’ website, but these are Basic Economy fares so keep in mind the multiple restrictions that entails.
