I am trying to fly from Boston to Munich for my friends’ birthdays in June. I have tons of frequent flyer mileage and I’m booking two months in advance so I thought I’d be in good shape. How naive. USAir has no seats. Delta has no seats unless I want to use 100,000 miles, which might be worth it since the ticket costs $1,374 (this is coach). The Delta agent told me I should have booked this about nine months ago. I did learn to use the fare search engines, kayak.com and yahoo farechase, which found me the cheapest fares of $869 on KLM or Lufthansa.
