Hi, first time on here and have been experimenting with ITA Matrix to do a TP run in Jan 24 to get Silver. Have found AGP-LHR-JFK-LAX-SFO (return obv) out 11 Jan back 14 Jan for around £1500. I thought it would be viable to do AGP-HEL-LHR-JFK-LAX-SFO as suggested in post seen in here but it's not taking it. Am I doing something wrong? Thanks for any help. HEL not actually reqd to get the >600 but just curious.
