So much for the outrage directed at United Airlines.

On Tuesday, the carrier released its first financial statement that included the period after security officers forcibly removed a 69-year-old passenger, Dr. David Dao, from a plane. The incident left him bloodied and disheveled and left United facing widespread calls for a boycott. Nearly three months later, it appears that all the public anger has not hurt the company’s bottom line.

United reported a profit of $818 million in the most recent quarter, ending in June, up 39 percent compared with last year. Sales rose, too, as more customers booked flights with the carrier, amid rising demand for air service over all. In a separate report this month, United said that it had more than 71 million passengers during the first half of the year, up 4.2 percent compared with last year.

The results point to an underlying principle about the airline business: Passengers, by and large, look for the most convenient and cheapest fares, not which airlines claim to offer the best service. The case of Dr. Dao and the initial public reaction put that principle to the test. A video of airport security officers dragging him off a flight on April 9 ricocheted around the world after another passenger posted it to Twitter. Dr. Dao’s lawyer said the removal, to make his seat available to a United employee, had left Dr. Dao with a broken nose, a concussion, two knocked-out teeth and sinus problems.
