President Trump announced — and celebrated — that Delta Air Lines revised its manuals to use “Gulf of America” for the body of water spanning Florida to Mexico in line with his executive order renaming the marginal sea.

The president shared a screen grab on Truth Social of an apparent “Revision Highlights Airway Manual” on official Delta letterhead, which Trump claimed he received from a Delta captain.

Key changes in the manual show that “Gulf of Mexico” is switched to “Gulf of America” and “Notice to Air Mission” is revised to “Notice to Airmen.”

“And the liberals thought Notice to Airman was racist to [sic] they changed it to Notice to Air Missions. Delta just changed it back to Notice to Airman.”

“I think they are finally embracing MAGA,” the commander in chief wrote.

Delta said it was simply complying with Federal Aviation Administration requirements.

“Those changes were mandated by the FAA,” a spokesperson for the airline said in a statement to The Post.
