sentences:  On October 29, 2016, the St. John's Airport Authority seized one of the aircraft of National Airlines passenger operations (N176CA, a 757), alleging non-payment for services at the airport during operations there.This was quickly followed by an announcement by the airline that they are cancelling operations into Newfoundland and Labrador as of January 6, 2017, and are also cancelling the substantial majority of flights scheduled for that route between October and the end of service.A hearing on the claim is scheduled.
