I'm incredibly skeptical. I think you missed the part of after all fees/taxes/everything. I mean I can look on Thomas Cook right now and see Toronto - London for $160 (+$739 taxes and fees)
I flew montreal-london my first trip and montreal-brussels the second trip.
and although whoever said France is a cheap place to fly into- its also the most expensive to stay in. Paris.. forget about it if you want a cheap trip.
I think it really depends on timing, but when I went this year it was cheap to fly into either Gatwick Airport in London or to Barcelona.
Also, if you can get to Hopfgarten in Austria I would highly recommend it. I went paragliding in the mountains and mountain biking on some unreal trails. Oh and apparently there's incredible skiing when there's snow...
When I visited this summer I went all over Europe. Personally I hated Italy it was the worse place that I went to on that trip. My favorites were, London, Switzerland, and Austria. I thought Belgium was all right nothing outstanding that's for sure.
