We also arrived on Saturday, around 4:30. There were two planes ahead of us, and we were in line for well over an hour. Thank God we were not stopped for carry on check after customs! It has always been hectic on Saturdays, but never this bad. We drove from Michigan to Toronto this year to fly Air Canada because it is a direct flight to SXM on Saturdays only, as opposed to flying from DTW with layover in Charlotte. But like you, we will skip Saturdays from now on.
