Since many seem to be in a “show me the price increases” mood and I have the luxury of one of the worlds largest database of current and historical airfare — I thought it might be fun to see how many comments it was possible to get on one blog post — so here is a challenge: I will post the 2008 price comparison information for the cheapest domestic U.S./Canada roundtrip business airfare (inside 14 days advance purchase) and leisure airfare for any city pair requested in a comment (1 per person per comment). I am heading to Seattle in a few months so I’ll make the first comment post (prices are the cheapest for the category that day including all fuel surcharges and 7.5% sales tax) :

A couple things to note:

• Sales do occur (contrary to popular belief) so this is just a snapshot in time
• Connecting air travel can use a combination of airfares from other city pairs which may be cheaper
• These are the absolute cheapest prices — airlines yield up to higher prices depending on the date/time of travel and projected demand
