I have a 241 booking to YUL in July. Also heading down to New York for a couple of days on an AA flight booked through AA. The return AA flight to YUL arrives a couple of hours before the BA flight to LHR (it was about 4 hours but due to AA schedule change it’s now only 2 hrs 35 mins. I’m wondering if there is any way to combine these bookings for baggage and also peace of mind with delays etc?
