The best day to buy cheap airfare is just one of the topics covered in my latest weekly column for ABCNews.com called “10 Things You Should Know to Get the Best Flight Deals”.

I begin the column this way:

“Flying is a pain. We all know that. The insane security demands, those preposterous bag fees. It’s gotten out of control. So the least the airlines can do is let us fly for cheap, right? And many times they do.” -Rick Seaney, ABCNews.com

Best day to buy? Usually Tuesday.

“Airfare sales usually begin with a single airline announcing new deals Monday evening. By Tuesday at lunchtime, the other airlines have matched those prices, meaning Tuesday afternoons are often the best days to buy. This is how it usually works, although sales have been announced on other weekdays.” -Rick Seaney, ABCNews.com

Best time to fly? At dawn or first flight out; at lunch time or the dinner hour; and overnights (red-eyes). More tips in the column.
