I recently booked a ticket through skiplagged and thought I had snagged a great deal. A few weeks later, I realized I had booked the wrong date.
I thought this was my own fault through haste - until I went back and tried to buy another ticket through skiplagged.
Take a look at this screenshot. - you'll notice one date searched for, another date given when actually choosing a flight.
The kayak and hipmunk links on the site went to the correct date.
Who knows if I actually screwed up my dates initially or I got caught up in the middle of a poorly programmed bait and switch? My fault for not triple checking the dates but I no longer consider it a reliable travel tool.
