I recently discovered Delta has changed its rules for accessing EC seats. I'm a Diamond Medallion member and in the past I could access EC seats at any time prior to travel. It appears the EC seats are now only accessible after actual ticketing. For me, that's a problem since my company usually makes reserverations weeks in advance but only purchases the tickets 72 hours prior. I may be one of few impacted by this but it irks me that Delta pushed thru yet another change to the program and didn't notify it's "members" and, unless I missed it completely, didn't publish this change very well. Did I miss the boat on this change?
