Hi. So, I am brand new here, but figured it was the place to go to ask some questions.

Next month I will be taking a 2 hour flight or so alone and it will be my first time needing assistance. I can't walk the equivalent of maybe a block and stand for about 2 minutes at a go on a good day. I know I will need to ask for wheel chair assistance. I am 18, but at times can easily be mistaken for someone who is 15 or a touch younger. I am nervous about the stigma of trying to get help when so young. Is there anything I can do/say to avoid the looks/comments/questions?

I also will not be able to lift my own bags. I may need to bring a bag as a carry-on as well because of cost. Will someone be able to help me on the plane or do I just have to hope I can flag down someone nice and ask them to lift them for me?

Is there anything else I should know? (I got that I should carry small bills to tip and always say thank you when I am getting help.)

Bother, I forgot to add that I look completely able-bodied, which seems to make people more upset.
