JetBlue flights are cancelled around the north east to let pilots get some rest time. Flights to and from Boston Logan International Airport and New York's three airports are delayed and cancelled.

Following a weekend of poor weather and with new Federal Aviation Administration rules on pilot rest times that went into effect JetBlue had to cancel most flights at Boston's Logan, New York's John F. Kennedy International Airport, New York's LaGuardia Airport and Newark Liberty International Airport in New Jersey, starting at 1 p.m. on Monday, CNN reports.

The airline said it would start operations again at 10 a.m. on Tuesday and would be back to normal by 3 p.m. The airline said the cancellations would give the crew 17 hours of rest time, which is good for them, but customers may not be able to find an available seat for as long as a week. The call center is taking a heavy amount of calls as a result, so they recommend travelers to rebook their trip or request a refund.

JetBlue said it was prepared for the new rules that require pilots to get more rest time but it wasn't ready for the added delays due to the bad weather.

"In the midst of us repairing those schedules disrupted by this week's winter storms, we're facing an additional challenge as new FAA rules went into effect for crew rest," JetBlue spokeswoman Tamara Young told CNN. "These rules further impact our ability to operate an already disrupted schedule, causing our pilots to 'time out' even sooner. As a result, additional cancellations are likely to occur as we work to reset the operation."

Pilot fatigue became a noticeable problem following the crash of Colgan Air Flight 3407 in 2009. The FAA announced that the rules would be changed in 2011.

Many other airlines have cancelled flights due to the weather but no others seem to be having problems with the new pilot rest rules. According the airline pilots union, the Air Line Pilots Associations, airlines were given plenty of time to adjust to the new rules.

"They had two years to anticipate this (work hour rule) and to adjust accordingly," Sean Cassidy, vice president of the Air Line Pilots Association told CNN. "So I think it's overly simplistic to suggest that they could ascribe this disruption -- which happens to coincide with this major, major winter snowstorm -- and just hang it all on that rule-making change."
