[08/13/2015 @ 7:43 PM] It looks like this fare is no longer bookable. I’m removing this one from the bookable deals list.
Delta and SkyTeam partners have round-trip flights from Houston (IAH / HOU) to London (LHR) for $738, with one connection. Flights from October to March 2016. Holiday Blackouts apply (No NYE).
Note: It’s possible to get this for $698 if you’re willing to add an extra connection and don’t mind the extra airport time.
