Finally going to meet my LD girlfriend. Any advice?

Hello! As the title suggests, I'm (F30) finally going to meet my long distance girlfriend (also F30). We're approaching our one year anniversary and as such, we booked a plane ticket for me to go see her (she covered half of the costs). We met online and she lives on a different continent, so it will be my first time seeing her in person. We're both very excited, but also nervous. It's a 25 hour flight. She's worried about my safety up in the air, I'm worried about missing home, feeling homesick, as happy as I am to see her. There are so many things we're excited about! No more timezone difference, for starters. Going on dates, experiencing a little bit of everyday life and not just sightseeing. Sightseeing is fun, but what I want most is just sit on the couch together and ask her what she wants for dinner, since I love cooking, especially cooking for my loved ones and my big dream is to cook for her. However, there's something I'm worried about, too. What if we finally meet irl and it turns out she won't be as attracted to me as she was online? What if I have some habits that annoy her? Things that are not so easy to spot unless you actually meet your person irl. We've been through so much together already, especially with my chronic illness and endless hospital visits that she's always been a part of, even before we became a couple. After I woke up from my surgery, she was the first person I spoke to. I trust her and yet this tiny bit of fear is there. I spoke to her about it a little bit, and while we couldn't give it that much time because it was late for her, she admitted she had the same fear - that perhaps I will see her differently once I see her in real life. She said she would love to talk about it more once we both have the time to do so. Do you guys have any advice for the first time meeting? Are we just two needlessly worried dorks? Thank you so much :)
