I usually do my homework whenever I’m looking for a good deal on airfare. I compare prices on sites like Kayak, and others. But even if you do your homework, there is not guarantee that a couple of days later the same airline you booked your flight with, will post a new lower fare on their website and then you are stuck with the price you paid.
So is there any way to protect your purchase against lower fares after you make your reservation?
I emailed several airline companies and asked them that question. Here is what each one had to say regarding their lower price guarantee policy.
