I lived abroad for a couple of years, so I got used to transatlantic flights pretty quickly. If I wanted to get home and to college, I had to make multiple connecting flights on my own. There was no way of getting around flying, unless I wanted to charter a boat to France I guess. The turbulence can sometimes make me feel sick, but I'm not particularly scared about being up in the air.
What I am scared about though, is missing my flight for some reason, or boarding the wrong one! I always have so much anxiety when I'm trying to go to the airport because I don't want anything to go wrong, so I actually feel better once I sit down on the plane and reassure myself that I made it.
One time, my friends and I made the glorious decision of booking a 7:30 am flight from Munich to Paris because it was a cheap ticket and it'd give us enough time to settle down before college started again. We had to wake up at 4am to pack our bags, eat a bit, and check out, then trust that the hotel remembered to book our taxi at 5:30 am in the morning (and trust that the driver would show up and actually take us there). You usually don't need to leave that early for inter-Europe flights because there's no customs, but we were just so scared that we left a lot of time in our schedule as a buffer.
Another time, I was travelling with my school from our home to Hong Kong, and our connecting flight in Taipei was significantly delayed. Like, our school's chaperone started texting the travel agent as soon as we landed because we thought we'd miss our connecting flight and need to find accomodations for 15+ people kind of delayed. We ran through the airport, but thankfully, since we were on the same airline and there were many people on our flight who were also delayed, the plane waited for us!
Though I would not have been opposed to spending the night in Taipei...
