|The WSJ report is in line with my own experience flying Delta from Rochester, NY to Amsterdam earlier this year. Most airlines, including Delta, cancelled flights during the pandemic, which often meant that a formerly non-stop flight often changed to one with a stopover. Delta allowed cancellation with no penalty, but the point is that the changes were for the convenience (and profit) of the airline, not for the benefit of the passenger.
Delta also demanded that anyone flying from JFK in New York to the Netherlands would not be allowed on the aircraft without a negative Covid-19 test, even though the Netherlands at the time required only proof of vaccination. Just happened that a Covid-19 test space in the Delta-owned terminal, near the gate for the flight to Amsterdam, was able to provide a rapid test for a mere $200 per person. If you didn't get the test, you wouldn't fly. Oh, and the testing place occupied a vacant store previously used by a spa that went out of business. The rental revenue from the store area goes to Delta.
Always new ways to make money.
