Drop in airline ticket prices today!

I bought a few weeks ago, my Italy tickets flying into Milan and out of Venice for $684 on Delta for a late fall/early winter trip, thinking that would be the cheapest I would get. Well, I just looked today and KLM has a sale going on. Same cities, $560. But I won't cry or complain. For $560, I would have to make 2 stops, instead of my 1 stop. And I would have to leave at the butt crack of dawn from Venice.

KLM is killing it!!!! Round trip From Tampa to Zurich for a late fall/early winter, $460!!!!!!!! Tamp.a to Barcelona, $506 round trip. Tampa to Brussels, $515 round trip.Tampa to Munich, $525. Attention all West coast Florida people........go to Europe end of November!!!!!
PS: I just did a lot of editing. Kept on seeing a lot of good deals.

The fare drop I mentioned was for the very same schedule I had gotten, with only one stop. The past two years I bought tickets in April for travel to Europe. This year I kept holding out for a price break which never happened until two days after I bought the tickets!

That is why I never check prices after I have bought the ticket!

As to checking fares after purchasing your tickets, my Kayak alert was still in effect for a few days after my ticket purchase, so that is how I found out about the price drop. I called Delta to ask for a refund of the price difference. The person said she could not do that, but could issue a voucher for the price of the tickets. I was very surprised to get two vouchers for $730 each which are good until July 1, 2011. So maybe that nullifies the idea of not checking on prices after purchasing tickets!

So you practically made out pretty good. Just becasue your flight became $200 cheaper, you will have 2 $730 vouchers to use for another trip. It almost seems too good to be true. Is this typical to be refunded (via voucher) so much more than the price drop?

These last couple weeks have been a roller coaster for fares. I looked 2 weeks ago... flights from Vegas to destinations all over Europe were about $600 r/t. Then, last week, they dropped to $450-$500 r/t (mostly on KLM). Great deal. So, I go back today to book my flight because I finally got our dates set, and the prices have soared to about $800.

Any logic to this madness? Any ideas if prices will dip back down to at least the $600 mark (even though the $500 would be great).

If I have gleaned anything from these boards, it's that airfare prices can fluctuate fairly unpredictably, because they are affected by the number of seats left with relation to how much time is left until the flight. What probably happened is: a bunch of people saw the $400-500 fare and bought seats, supply dropped, and hence the $800 price today.
