Foggy Monday morning at Fort Lauderdale-Hollywood International Airport caused diversions and delays

Miami-Dade County, Florida. – At least 25 flights were impacted because of visibility. Some of those flights were landing in Orlando, Fort Myers, or other Florida airports until the weather cleared up.

Close to 2 million passengers are expected from now until the end of the month at Miami International Airport.

“We are just getting started flying for the holidays,” said Ianta Summers, who was traveling through MIA. “We have other places to go too.”

Airports say parking is available but limited and asking travelers to leave extra time for parking and getting to their gate.

Gabe Zeinoun and his family flew to Miami from Boston for a get-together and are now heading back home in the midst of the holiday rush.

“There’s a lot of people. It’s pretty crazy,” he said. “There is a big rush I guess because COVID this year being more lax. Everyone is out traveling, it does seem like that.”

Health officials are urging everyone who is eligible to get vaccinated and get booster shots.

“The hope is that it will reduce those breakthrough cases, reduce hospitalizations, reduce deaths, reduce transmission and severe illness,” said Dr. Jen Ashton, ABC News chief medical correspondent.

Monday also marked the deadline for Transportation Security Administration workers to be vaccinated against COVID-19. According to TSA, 93% of employees are in compliance and that the mandate will not impact holiday travel.
