DAL Delta Air Lines Inc

Issuer Free Writing Prospectus filed pursuant to Rule 433

Registration Statement No. 333-216463

Pricing Term Sheet

Dated October 21, 2019

The information herein supplements the Preliminary Prospectus and supersedes the information in the Preliminary Prospectus to the extent inconsistent with the information in the Preliminary Prospectus.

Unless otherwise indicated, terms used but not defined herein have the meanings assigned to such terms in the Preliminary Prospectus.

It is expected that delivery of the notes will be made against payment on the notes on or about October 28, 2019, which will be five business days (as such term is used for purposes of Rule 15c6-1 of the Securities Exchange Act, as amended) following the date of pricing of the notes (this settlement cycle is referred to as “T+5”). Under Rule 15c6-1 of the Securities Exchange Act, as amended, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of pricing or after such date but before settlement occurs, may be required, by virtue of the fact that the notes will settle in T+5 to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to make such trades should consult their own advisors.

The issuer has filed a registration statement (including a base prospectus and preliminary prospectus supplement) with the SEC for the offering to which this communication relates. Before you invest, you should read the base prospectus and preliminary prospectus supplement in that registration statement and other documents the issuer has filed with the SEC for more complete information about the issuer and this offering. You may get these documents for free by visiting EDGAR on the SEC Web site at www.sec.gov. Alternatively, the issuer, any underwriter or any dealer participating in the offering will arrange to send you the prospectus if you request it by calling Barclays Capital Inc. at 888-603-5847, Citigroup Global Markets Inc. at 1-800-831-9146, J.P.
