Ok I'm looking to book a one way fare Paris- Exeter UK April 7. I've been watching the fare to see if it will come down, it's currently at 190 Euro, which I think is high for a one way short flight. The flight is basically empty, 3/4 seats are still showing empty. Today is 3 weeks out, I don't understand why they don't lower the fare to sell some seats, dare I wait a few more days or buy now??
