I had three trips planned from January to April from Europe to the US, flying United and other US Airlines, some parts in F. My plans are cancelled for the time being. Unfortunately one of my trips (FRA to BOS, CHI, NYC) is already booked on a non-refundable ticket. I guess I will take those flights, but after that I will spend my time and money(!) in countries where authorities aren't completely insane.
Too bad, I was especially looking forward to my trip to Puerto Rico in F in March.
I'll write emails now to United Airlines (and the other Airlines I planned to fly on), to explain exactly that.
edit: oh, does someone have an email adress I can send this to (maybe as well for CO and US?)? I don't like these web forms...
