- IB 6117 MAD 4:35 PM MIA 8:30 PM
- IB 2625 BCN 6:35 PM BOS 9:15 PM
- IB 2627 BCN 6:55 PM JFK 10:00 PM
- AY 15 HEL 5:20 PM JFK 7:05 PM
- BA 239 LHR 8:10 PM BOS 10:30 PM
- AA 141 LHR 7:55 PM JFK 10:43 PM
- BA 183 LHR 7:05 PM JFK 9:50 PM
- AA 139 0 LHR 6:50 PM LAX 10:04 PM
There should be LHR-BOS on a Sunday night. Also you could try departing from HEL, MAN, DUB etc.
But your best bet would be to sign up for ExpertFlyer and do your own searches - it is very fast once you get the hang of it.
I went ahead with the
BA181 LHR-EWR option.
Thank you for your help! I know feel confident that it's the best choice for my travel needs this time.
