I am looking to book a one way flight from either Pisa (preferably) or Florence to Paris on Sunday, May 17. When I looked at these flights a month or more ago, I swear they were ~$90 each. Now they cheapest one from Pisa is $265! And that flight goes to Paris Beauvais which appears to be 1.5 hours from Paris center! There's a nonstop to Orly in the afternoon and it is $412. Flying from Florence isn't any better.
If we fly on Monday, there are options between 100 - 200. What is going on that Sunday that is driving up prices??
