Flight chaos looms at Logan as FAA cuts flights

State of play: Massport confirmed Thursday that Logan will be affected.

• But state officials don't know which flights will be canceled and are waiting on the FAA for details.
• "For those traveling over the next few days, we do anticipate delays and cancellations and strongly urge passengers to check with their airline before coming to the airport," a Massport spokesperson said in a statement.

Threat level: Logan could see dozens of flight cancellations Friday, affecting up to 6,200 passengers, aviation analytics firm Cirium told GBH News.

• That's 10% of Logan's typical daily 500 departures carrying 62,000 passengers.

The big picture: Air traffic controllers have been working unpaid since the shutdown began Oct. 1.

• Controllers face their second missed paycheck Friday. That creates mounting financial pressure and staffing shortages.

Of note: Airlines say they will offer flexibility during the disruption.

• United, Delta, American and JetBlue, which each have a big presence at Logan, said they'll refund canceled flights, including for non-refundable tickets.
• Carriers expect regional flights to bear the brunt of cancellations while preserving international and hub-to-hub routes.

What's next: Massport says it is coordinating with the FAA and airlines to minimize disruptions but expects conditions to worsen if the shutdown continues.
