I'm booking an international flight for a scheduled vacation next January. About a month ago, I found a fantastic deal at around $450 but back then my schedule wasn't fixed so I let go of it. 2 weeks later when I searched the same flight on the same travel portal, it was 850. I let go again to speculate. 3 days ago 450 dollar fare showed up again, I tried to book but got called up for some shit and forgot about it. The next morning it went back up 850. I wonder the price tend to fluctuate and come back again....After seeing that 450 dollar fare (it's the same seating class, same airline btw) I can't buy anything above that!
