Delta has unfortunately chosen to remove all of their upgrade inventory from ExpertFlyer and as such it is no longer available at this time. This is after previously being authorized by and told by Delta that upgrade inventory would continue to be made available. As such all Flight Alerts for the affected upgrade classes will be set to Expired later today as to not count against your active alert limit. We will then email ExpertFlyer subscribers that currently have active DL upgrade alerts to notify them of this change.
To be clear, not only was the data legitimately purchased via our GDS data contracts, but executives at Delta were aware that ExpertFlyer was showing DL upgrade inventory and we were allowed to continue doing so until a recent policy change.
We agree with the sentiments of our customers that ultimately this does more harm than good to their best customers and suggest that you contact Delta and express to them how you feel about the ability to see, evaluate and use these various upgrade inventories and the value it adds to your elite status with Delta. Please use the following link to email them.
