Hello ... hoping some dis'ers can tell me sites you go to for comparing the cost of flights or booking? We want to fly from the US, but I am going from site to site to site trying to compare cost. Last year we flew out of Cleveland and had great rates and we can do that again this year with Southwest for $1400 for the four of us. Out of Detroit it is just over 1600 and out of Buffalo is almost $2900!!! We live about two hours north of Toronto, so driving takes about 3 hours to Buffalo, maybe 5 to Detroit and six to Cleveland. Not sure what to do ... One year we waited and booked last minute at Christmas time and got a great deal from Jet Blue out of Buffalo for the March Break. I don't know if that would ever happen again. So where do you fly from and what sites do you look up flights on and compare them? I"m frustrated!
