The partial shutdown of the federal government is taking its toll on airports.

On Saturday, Miami International Airport closed one of its security checkpoints because airport officials were worried there wouldn’t be enough TSA employees on duty to keep all the airport’s checkpoints open.

Due to the federal funding lapse, some passengers may experience changes to their security checkpoint & departure gate. Security checkpoints are running smoothly & we don't anticipate any significant impact to flight schedules or passenger experience. https://t.co/ovYidvZrCU pic.twitter.com/QmlforQA3J

The airport plans to reopen the checkpoint on Monday morning.

MIA’s Concourse G will return to normal operations on Monday morning, with the TSA fully staffing the Concourse G checkpoint. MIA and TSA will continue to monitor checkpoint staffing levels and make adjustments as necessary. pic.twitter.com/TEMTw2jTyH

On Sunday afternoon, Houston’s George Bush International Airport (IAH), shut down the TSA checkpoint and ticketing counter in Terminal B. The reason? Concern about staffing issues associated with the partial shutdown of the federal government.

The closure of Terminal B ticketing lobby and security checkpoint is currently scheduled to last until the end of the day. For more information, go to: https://t.co/V7pe3Uruvk #fly2houston

If the government shutdown continues, we can expect more of these checkpoint closures to take place. Passengers will be directed to other checkpoints, where lines will no doubt get very long.

And outpouring of pizza

While long lines are surely frustrating for travelers, there is an outpouring of support for the TSA workers, air traffice controllers and customs and border protection workers who are working without pay.

On Friday, Nashville International Airport sent pizzas to TSA employees at the airport working without pay.

We’ve got a trunk full of pizzas heading to our friends at @TSA. It’s not much, but just a small token to say thank you for keeping our airport running. We appreciate YOU! pic.twitter.com/i01p5drJJ1

And Canadian air traffic controllers showed their support for their American counterparts by sending pizzas as well.

“…all seven of Canada's area control centres had sent pizza to American colleagues, along with many of the country's 40 control towers.” https://t.co/hjRqnRTIjW

Remember Gander, the tiny town in Newfoundland that opened its hearts to 7,000+ stranded Americans on 9/11?

Their air traffic controllers just sent pizza to their American colleagues – to help them out during the shutdown

Now every Canadian ATC tower is doing the same.

Elsewhere, there’s a pop-up food pantry for TSA employees at Tampa International Airport.

We look at our TSA partners as a part of our TPA family and hope to help them during this time. https://t.co/0FFUn3NJKu

At Your Gate is offering $10 off and waiving the delivery fee for food delivered to TSA employees on duty at Newark Liberty International Airport (EWR). The offer will expand to other airports where the service is available (San Diego International Airport, New York LaGuardia Terminal B, JFK and MSP) later this week.

Federal workers working without pay at Ontario International Airport were treated to a barbecue on Friday. Food was supplied by the Ontario Reign Hockey team and other groups in town.

On Friday, Pittsburgh International Airport served lunch to federal workers at the airport and plans to do so each Friday until the shutdown is over.

Across the country, @TSA workers will miss their first scheduled payday today due to the #GovernmentShutdown. To say thanks, PIT is providing more than 200 free lunches for federal workers on Fridays until the government reopens. More here: https://t.co/0oIOAypftQ pic.twitter.com/RtnmkZ2F8j

Seattle Tacoma International Airport will hold its second information fair on Monday to help federal employees working without pay learn about short term loans and other resources that may be available to them.

And, as we reported earlier, Hudson Group, which operates shops in many airports, is offering a 20% discount off food, beverages and many store products to all TSA and customs employees until the shutdown is resolved.

OTG, which operates retail outlets and restaurants in 10 airports, will offer TSA employees a 50 percent discount on food and beverage through the duration of the government shutdown too.

If you learn of any other efforts underway, please let us know.
