I have flown the US carriers many times..but I swore after last winter trip, never again, at least in the winter. My car was encased in ice upon our return to Buffalo and it took ages to get inside. Then the wipers snapped off so it was not a great ride home. All this and I have auto start - so that started & warmed the car so we COULD get inside and heated washer fluid to help melt the windshield!

It was awful...
We paid under $1,700 for all 4 of us YYZ-FLL non stop, taxes incl so I am pretty happy with that.
