Hi all. This is my first post on Milepoint. I searched for similar threads but didn't find anything. I'm pricing a flight from MDT to SJU from Saturday 26 May 2012 to Wednesday 30 May 2012 and am getting prices from ITA that don't match the Delta website. If I search using the "calendar of lowest fares" and the advanced routing codes CL* or CL+, I can get flights costing $501 to show up. If I search without using the advanced routing codes, I get pricing at $503. At Delta.com, the price is $584.40 for the exact same flight numbers. This has been going on for a few days. Is this a common occurrence with ITA software and Delta? Thanks very much.
