For some time now I have checking Delta's "best prices" against Kayak.com.
Today I priced a ski trip from RSW to BZN 2/19-2/24. Delta's prices was $1064 and Kayak was over $400 less. I have booked Delta flights on Kayak a number of times and saved a good amount of money but never this much.
In fairness Kayak.com uses more creative routings using Delta Connection flights and I have generally had travel plans with more legs.
That said, I use the same day confirm privileges to straighten out some of the routings or I just relax and collect the extra miles
Makes me wonder why I just can't get Delta's best price directly from them.
