After being confined inside two planes on a Montgomery tarmac overnight on Thursday, nearly 300 passengers flying out of Mexico were able to reach their intended Atlanta destination early Friday morning.

Boston’s Lauren Forbes was bound for a layover in Atlanta when their plane was diverted to Montgomery because of inclement weather, she told WCVB.

And because the Montgomery Regional Airport doesn’t have customs, passengers on the two diverted flights, Delta Flights 1828 from Cabo San Lucas and 599 from Mexico City, were forced to remain inside the planes overnight.

“I guess the law is that if there’s no customs at the airport, you are literally stuck on that airplane,” Forbes told the publication.

“So, I just learned that today.”

The airline said that Birmingham-Shuttlesworth International Airport was not suitable because of storm conditions in that area, according to Forbes.

150 customers were aboard Flight 1828, which departed Cabo San Lucas at 5:17 p.m. and landed in Montgomery and arrived to a gate at 10:34 p.m., Delta said in a statement to WCVB. The release said egress was available for those passengers at 5:23 a.m.

Another 147 passengers were aboard Flight 599. They departed at 6:16 p.m., reached a gate in Montgomery at 10:22 p.m. and were held on board until 5:15 a.m, according to Delta.

Once the passengers were brought inside, they were confined and guarded inside the airport since they hadn’t gone through customs, Forbes told WCVB.

Flights were available out of Montgomery to Atlanta starting after 4:00 a.m., according to the airport website.

From there, Forbes said that her boyfriend had to get on the phone to book their final leg home to Boston.

“We sincerely apologize to our customers for this experience,” a Delta spokesperson wrote in the statement to WCVB.

“We fell short of how we aspire to serve and care for our customers amid thunderstorms in the Southeast U.S. Thursday evening. We are reaching out to each customer with a full refund of their booking.”

Efforts to reach Delta for comment were not immediately successful.
