The Airbus A320 crash-landed in the Hudson last week after hitting birds and losing thrust in both engines. All 155 people on board survived. The rest of the plane was taken to a New Jersey marina over the weekend.
The airline has sent $5,000 checks to each of the 150 passengers to compensate them for lost luggage and other belongings.
In a letter sent to passengers, an airline executive said she was "truly sorry." The letter also explained that passengers' belongings left in the plane could be stuck with investigators for months.
The airline also said it would reimburse passengers for their ticket costs.
