I’m looking to buy an open jaw trip travelling (maybe double open jaw) outbound LHR-PHL / returning ideally from somewhere in north-east USA back to anywhere in Europe.

Constraints are that the LHR-PHL must be on the morning flight AA729 on June 27th so that’s only a little more than a week away.

The other flight could be on almost any Thursday evening starting late this autumn into 2025.

The best price I’ve found seems to be $868 using JBA fares with JFK-LHR as the other leg in Feb/Mar 2025. BA and AA coded tickets price as identical or nearly identical. I tried other originating points (BA cities served in the USA) and also other destination points like MAD/BRU/CDG and lots elsewhere in Europe but they all price much higher. Seems like you can’t combine the LHR-PHL with a double open jaw JFK- anywhere other than LHR and get a price lower than about $2000 which defeats the aim of finding a lower fare than $868.

Ideas?

My $868 example using AA729 / BA172:
