ExpertFlyer has displayed some Delta information, including some award availability, for about a year:
We're happy to announce that the previously missing DL data has been restored to ExpertFlyer. The only exception is that DL Upgrade inventory, which Delta is still not allowing access to, is not available. However regular fare class inventory/availability/alerting and all other searches (Seat Maps/Alerts, Fares, etc.) are available again for DL. This is in addition to the previously released low/saver-level DL Award inventory.
Please note, for the Flight Availability search, DL flights will only be returned when DL is the only airline specified in the search.
