We normally fly Virgin, but prices were too high, we ended up booking with expedia and flying from Heathrow by Air Canada to Montreal, then Air Canada to
Orlando, on the way back air Canada via Toronto, I must admit I was not looking forward to it, but turned out great
These are the flight s we used, I used this to keep track of the times, first one is the flight to montreal second is down to orlando

Upon arriving at Heathrow, I had vowed that I would go to a check in desk to ask questions re luggage going all the way through, but straight away was directed to a machine.
Enter air Canada booking ref, supplied BY EXPEDIA
straight away it comes up with your 2 outgoing flights, get your passports scanned, it then issues your boarding passes for both flights, together with you luggage tickets, go to check in desk, she weighs luggage, and that's it.
On arrival at Montreal, follow the connecting corridor to usa flights
go through security/xray machine carry ons
Then passports are scanned in self service machine (5 mins)
take seat in front of large tv, all the names of your party will be in orange, when they go green that means they have photographed your luggage
proceed 20 ft to Us immigration, took 5 mins, then straight into departures.
coming back was even easier followed connections corridor at arrivals, passports stamped then straight into departures, it was so easy we were like "that cant be it, we must have missed a bit"
Will def do again, the first flight was 6 hours, seemed shorter, and arrival in Orlando was so so easy and the money we saved paid for spending
I was worried the lay over at Montreal would not be long enough, being 1hr 40, but it was fine,
