Thanks for the replies everyone! It turns out my flight to Toronto Thursday night was delayed by 4 hours, making me miss my connection in Toronto for my flight to Heathrow. There were no more flights out that night so they flew me to Toronto, put me in a hotel (which I only used for 3 hours) and then I left Toronto in the morning. I asked them to check in my second bag for free because of the inconvenience, and they did
When I was finally was on my flight to London, a flight attendant asked me do a favor for her to make another passenger happy. I offered to, and she gave me a fast track pass! I've never had one, and woah, are those things like GOLD. When I approached the immigration lines, the Non UK/EU line was probably 200 people long, and looked like 2 hours wait. The fast track line, I walked right up and was in within 3 minutes. From the time I got off the plane, went through immigration, got my bags and got to my boyfriend- it was probably 20 minutes!!! My BF was SHOCKED that I got out so fast! It was so nice that after 5 trips here, I finally got a break and didn't have to wait in that awful line.
