Mr. Rob Hawks Attorney, Regulations Division

Federal Aviation Administration Office of Chief Counsel 800 Independence Avenue, S. W. Wa shington, DC 20591

Dear Mr. Hawks,

In light of our slot waiver request, further review of the usage report submitted to the FAA identified several slot transfers that should have occurred between Delta Air Lines and our Delta Connection carriers. D ue to the numerous cancellations and subsequent repositioning of aircraft and other network recovery initiatives during the excessive snow storms, many unplanned schedule changes transpired.

Due to these extraordinary circumstances, we neglected to subm it these transfers in advance. In normal course of business, our schedules are planned months in advance and slots are assigned accurately to the appropriate carriers. W e will continue to be on the alert to accomplish any needed transfers of slots due to unexpected, close

- in situations to prevent this from happening in the future. We have scheduled further reviews of slot compliance and accuracy to ensure this situation will not happen again and do not expect this to be an ongoing situation.

W e respectfully request retroactive transfers of operations by our Delta Connection partners wh ich are listed below. Confirmation of these transfers, and granting of the waiver request on file, will result in the following slots meeting the 80% utilization requirement for January and February.

### Finally, we understand certain traditional off

- peak slot times at DCA were below 80% utilization (0600 and 2200 hours). In practice, these slots ha ve not been precisely monitored due to their availability; however, given new increased demand and inquiries, Delta Air Lines has taken immediate action to maintain utilization requirements within these hours

, in f uture. I hope this can resolve any concern s of under

- utilization of these slots during past usage periods, as well. See transactions sent in to FAA on July 20, 2011 wh ich are listed below:
