As a possible legislative solution to the federal shutdown made its way through the Senate on Monday, travelers at the world’s busiest airport faced challenges.

A Delta Air Lines pilot shared a heartfelt message with his passengers, assuring them that everything will be OK.

Delta Air Lines will comply with an FAA order to cut flights at 40 major U.S. airports starting Friday, likely including Atlanta’s Hartsfield-Jackson, while offering flexible options for travelers affected by the reductions.

Air travel is struggling as the government shutdown causes hassles and uncertainty for travelers, disruptions for airlines and even less wiggle room to recover from problems.

ATLANTA — Hundreds more flights appear to have been canceled Sunday at Hartsfield-Jackson Atlanta International Airport, a day after a similar waive of cancellations that have begun with the FAA saying it would institute service cuts at the nation's busiest airports amid the ongoing government shutdown.

Hartsfield-Jackson remains fully operational but is seeing hundreds of cancellations and widespread delays amid the federal shutdown.
