United Airlines on Tuesday said that they will not consider firing any employees involved in the passenger dragging incident that happened on its flight from Chicago to Louisville in Kentucky on April 9.
It's too soon to say whether the incident has affected customers' willingness to travel with United, particularly since it happened during the week before Easter, when the airline typically sees fewer passengers, executives said.
Dao's lawyers have taken steps that foreshadow a lawsuit against the airline and the city of Chicago, which operates O'Hare Airport.
United has repeatedly apologised for the incident and announced two rule changes last week, including saying that it will no longer call police to remove passengers from overbooked planes.
"Whether it is overbooked planes, delayed flights or sky-high fees, the laws we have now in place to protect consumers have been frequently and flagrantly ignored by airlines more concerned with profits than passengers", said Blumenthal.
"The incident on board Flight 3411 has been a humbling learning experience for all of us here at United and for me in particular", United CEO Oscar Munoz said.
An engaged couple were removed from a United Airlines flight to Costa Rica on Saturday, as the airline remained under scrutiny following outrage caused by a video last week of a passenger being forcibly removed from a flight.
Even in normal times, airlines closely - even daily - scrutinize numbers such as advance sales and occupancy levels on planes.
United President Scott Kirby said that "it's really too early for us to tell anything about bookings", while noting that the company's April-June financial forecast had not changed.
United Continental Holdings Inc reported sharply lower first-quarter earnings Monday.
Dr David Dao sustained a number of injuries during the incident.
Call it the new spirit of contrition at United Airlines.
Other airlines have chose to increase their compensation offers for such passengers.
United serves about 20 percent of the total US-China traffic and has a partnership with Air China, the country's third-largest airline, according to analysts.
"We felt pretty good about the communications that we've had so far and our ability to reassure them and explain things like overbooking", Kirby said.
