So I'm coming back to the US in June, and my Mom and Sister want to go to Montreal for a few days [June 12 - 16] from New York. Time is limited so we are flying instead of making the drive upstate. My Mom has to leave on an earlier flight coming back in order to be at work on time. I go to AmericanAirlines.com [Travelocity is showing that they are the cheapest] and see that almost all of the flights are for 216.00 + taxes and fees. This appears not to be a heavily traveled route, and is serviced by American Eagle instead of regular old American. The planes are small and only hold 42 passengers. The flight time is a whopping 1 hour and 25 minutes. I purchase tickets for my sister and myself. A couple of hours later I go to purchase the ticket for my Mom, and most of prices have shot up to 295.00 + taxes and fees for most of the flights - with a few still left at the 216.00 price. Unfortunately, those remaining cheaper flights don't fit into our schedule. I think to myself - this is bulls%*t. My purchasing two lousy tickets has set of some sort of chain reaction. I figure I'll wait for them to come back down. I check today, and all the flights have shot up to 360.00 + taxes and fees. This is beginning to piss me off because we are looking at $400 with all the taxes and fees. My flight from Frankfurt to NYC only cost $545 total. I don't understand the sudden increase in price. When I look at the seats available for the flight back for my Mom there are only 9 seats filled out of 42. On the flight there, only 14 out of 37 are filled. What gives? I can't imagine there was a sudden rush on these flights in the space of 30 hours.
