Farecast Summer Airfare Strategies: a very pedagogic video

Folks at Farecast blog give us a very interesting video about Summer Airfare Strategies.
According to the blog:
The video covers domestic travel and travel from the US to Europe, with a focus on summer travel strategies.
Tips include:
* how much extra you can expect to pay at different times of year
* which months are the best time to fly
* how day of the week influences ticket price, and how the effect varies by season
You will learn prices can go up to x 2.5 during pic season time in Europe and discover nice graphs and more…
I am wondering if this stats from 2007 can be the same for 2008.
Financial crisis in US, Dollar exchange rate will have a impact for the american tourists who want to travel to Europe.
What do you think?
