EDIT-I don't have anxiety about flying or the safety of it. It's more about being embarrassed because my fiancee's family has much more travel experience than me and I don't want to make a fool of myself in front of them or look like a pleb/moron. I already have Real ID and have had it since 2018.

2ND EDIT-My fiancee's family know that I come from a family that had financial struggles and they know certain details such as family being on food stamps at one point, me having thrift store clothes. they know about my mom having struggles trying to get SSDI. But they are certain things they don't know such as me being homeless at one point as an adult after a job loss. I don't want them to know everything about my past struggles and my family's past struggles.

I have never flown before. My fiancee invited me on a trip with her and her family for a family reunion in July.

I'm pretty much a moron when it comes to traveling as I grew up in a family that had money struggles (dad was a police officer in a smaller city that didn't pay well and mom was diagonsed with multiple sclerosis and could only work part time and there were financial issues caused by her MS).

I asked my fiancee not to say anything about my lack of travel experience to her parents and two brothers who are traveling with us.

I want insight/advice from experienced travelers and I don't want to ask my girlfriend because she has already agreed to not say anything to her family about me having zero travel experience.

Please be kind, it's already embarrassing for me to have never traveled via plane.

I got engaged last month. My fiancée and I are in the early stages of planning.

I don't have any brothers. I only have sister who is three years older than me. Our father was career Air Force and we moved around every 2-4 years. So it was a bit hard to make long term friends. I graduated from college with a criminal justice degree and went to a police academy. During my time in the police academy, I became close friends with a guy who was an Army brat and understood some of the things I went through. I will call this friend "Kyle". "Kyle" didn't have brothers either. He got married in 2017, and I was the best man. In 2019, I started showing symptoms of multiple sclerosis. I ended up leaving law enforcement after my diagnosis. I now work in the tech field. My friendships with "Kyle" and other LEOs" changed a after I left law enforcement because they are dealing with difficult work and I changed to an easier career path. I'm not as close to Kyle as I was in the past. Don't get me wrong, I will always value the friendship we built at the academy and working together in LE, but things are different these days and we are in different places.

I also went through rough times dealing my MS diagnosis and became closer with my sister, some cousins, and my parents. My sister was there for me during some rough emotional times. I'm considering making my sister "best woman" in my wedding and having Kyle as a groomsman. I do worry about "Kyle" being hurt because I was best man in his wedding.
