Delta executed a smooth holiday travel week for more than 3.6 million customers, with the airline setting a post-downturn record for a single day on Sunday.

Those 3.6 million customers traveled on more than 32,000 flights from November  21-28. Sunday, November 28, saw the highest volume with 534,000 passengers traveling on more than 2,700 flights.

Only 16 flights (out of more than 27,000 scheduled Delta flights systemwide) were canceled from November 22-28, while Delta Connection boasted an 11-day streak of no cancellations in November.

Figures for the full holiday travel period of November 19-30 are still pending and will be released as they become available.

“As many customers return to travel for the first time, they are experiencing our superior performance and service that Delta people are known for, to kick off what is another busy travel season,” said John Laughter, E.V.P. and Chief of Operations.

The Transportation Security Administration said overall volume from November 19-28 reached 89% of pre-pandemic levels, with 20.9 million passengers screened. That number reached more than 2.4 million on Sunday, November 28, which TSA called a new high since the pandemic began.

December Holiday Outlook

For the period running December 17-January 3, Delta expects to fly 8.7 million to 9 million passengers — an average of 490,000 per day. Six to eight of those days could come near the single-day post-downturn travel record set on November 28, with peak averages of about 530,000 per day. 

Editor’s note: This story has been corrected to show that 16 flights were canceled, not 17. Additionally, Delta Connection boasted an 11-day streak of no cancellations in November, not 12 days.

These early projections are subject to change. This story may be updated as new data becomes available.
