Do you book midweek or weekend airline tickets?

[Mr. Twister]

I am finally going to get a countdown soon! Hurray!

I am trying to go through all the insane airfare prices & make a decision. As we all know midweek travel is a lot cheaper. For me I can save about $170 per ticket to travel midweek. I'm trying to decide whether its worth the extra $340 total to get to extra 1-2 days but cover two weekends. The cheapest days for me to book are Tuesdays and Wednesdays.

I'm curious...what do y'all do? Book midweek to get the best fares or spend the extra to get more time?
