Delta Air Lines said on Wednesday that it was offering $30,000 to each passenger who was aboard the flight from Minneapolis that crashed and flipped upside down this week while trying to land in Toronto.

All 80 people — 76 passengers and four crew members — who were on Delta Flight 4819 survived after the jet made a rough landing and rolled over, ending belly-up with its right wing sheared off at Toronto Pearson International Airport on Monday.

Of the 21 passengers who were taken to hospitals, all but one had been released by Wednesday morning, Delta said. None of the passengers had life-threatening injuries.

Delta confirmed on Wednesday that it had made the $30,000 offer to passengers. Its representatives were telling the passengers that the offer came with “no strings attached and does not affect rights,” a company spokesman said via email.

It came as Rochon Genova, a Canadian law firm, said it had been retained by some of the passengers.

Days after the crash, officials have released few details about the investigation. On Wednesday, Ed Bastian, Delta’s chief executive, said in an interview on CBS that the flight had been staffed by an “experienced crew” but provided little further information.

On Wednesday evening, what was left of the aircraft was removed from Toronto Pearson International Airport, Canada’s busiest, where it had been blocking the two longest runways, Delta said.
