I would like to viist family from LHR and we'd be leaving from the YUL/YYZ/JFK/BOS/EWR area. Last year I booked a ticket 4 months in advance with my then gf (Now ex) and she broke up with me a few months before our trip. I went going by myself and enjoyed it but still it was a complete mess. Maybe I'm stupid (but thats another post for another time), but my new gf and I would like to go to LHR. Her mother is willing to help with the money, however I am very anxious about booking 4 months in advance again. We'd be there for xmas and right now its fairly cheap out of YUL. I was wondering if it would be very expensive to book 4 weeks in advance to prevent a repeat. We;d be leaving a few days from xmas and returning a few days into the new year.
Thanks for your help!
