I just looked at prices for a round trip ticket from San Francisco to Montreal for Monday. It was $389. I've never seen such a low price for buying two days in advance.
It's only going to work for customers who have to fly - which is a fairly small number. So instead of making up a shortfall, it's more likely to be a money-losing strategy.
I checked our local carrier and prices are down a lot. I was considering a flight at the end of April and prices are between a half and a third of what they were when I checked them in January.
What's going on?
The airlines have changed their rebooking policy to make it much more lenient for the next few months. Maybe this is making the tickets more valuable and pushing up the price?
The trouble is that this will drive out the holiday flyers and leave them dependent on business flyers whose companies can turn off the tap on a whim. And will have every incentive, and excuse, to do so.
