I frequently fly out of FAR or MSP to Europe. Most trips are 5-7 days. I've been doing this for years - and I always run into the same problem: Flights less than 7 days are at least 2x the price as a 7+ day trip!

The only good workaround I've found is booking trips in opposing pairs. Example: an April 1-5 trip and a May 1-5 trip.

• Ticket 1: A-B April 1 and B-A May 5
• Ticket 2: B-A April 5 April and A-B May 1

This makes both trips > 7 days. I can often book two tickets like this for the price of one! But it's tough if I don't have two consecutive trips to book.

Does anyone have any other tips? (Must be on Skyteam)

Also - any idea why the < 7 day trips are so expensive? Appears not to be taxes/fees, it looks like Delta is gouging workweek business travelers
