So it took me an infinitely long time to arrange my flights and select which felt like they might be good dates. Difficult. And right at the end United Airlines didn't accept Paypal after all. I did all this research and found their page where they are so proud of offering paypal payment options. Nonsense. It was nowhere to be found when I looked for it. So my poor squealing credit card had to stand in once more.
Now I have my ticket. Finally there is a clear schedule! I will relax as soon as I have booked my travel insurance. The silliest things have the power to stop one from flying. So I would like to be prepared just in case. And taking a trip to America without travel insurance would be pure madness anyway.
