Alaska Airlines issued a travel advisory Sunday, warning of flight delays caused by government budget cuts.
Alaska estimated the largest impact for Alaska Airlines would be seen by customers traveling to, from or through San Diego (SAN), San Francisco (SFO) and Los Angeles (LAX) airports.
Customers were encouraged to monitor their flight status before leaving for the airport.
Information from the FAA and others showed that flying Sunday was largely uneventful, with most flights on time. There were delays in parts of Florida, but those were caused by thunderstorms.
Mark Duell at the flight tracking website FlightAware said that John F. Kennedy and LaGuardia airports in New York indicated delays due to lower staffing starting late Sunday evening. JFK averaged 70-minute delays for inbound flights, but no detectable departure delays. LaGuardia averaged 74-minute delays for inbound flights, and departure delays of 37 minutes.
The FAA website said that flights from Philadelphia and Orlando, Fla., into John F. Kennedy, LaGuardia and Westchester County airports were delayed due to staffing issues.
The trade group Airlines for America, which represents the airlines and had predicted a big traffic snarl, said Sunday evening that it was "not seeing a significant impact at this point." A spokeswoman said the group would continue to monitor the situation, and urged flyers to stay in contact with their airlines.
Government budget cuts that kicked in last month are forcing the FAA and other agencies to cut their spending. FAA officials have said they have no choice but to furlough all 47,000 agency employees, including nearly 15,000 controllers. Each employee will lose one day of work every other week. The FAA has said that planes will have to take off and land less frequently, so as not to overload the remaining controllers on duty.
