Hello to all,

Apologies if this has been asked and answered elsewhere, but I wasn't able to find a similar thread by searching.

So, due to being a person and living life, I've reached a point where I now need to walk with a cane and I'm a lot slower than I once was. I have been doing so for about 6 or 7 months now, but I'm about to fly for the first time since becoming disabled.

I'll be flying with United (domestic USA travel), and I am wondering if I need to bring any documentation with me to show the gate agent in order to take advantage of pre-boarding? Their website doesn't say much. Do I need a doctor's note? Handicapped placard? Something else? None of the above? I just want to make sure I've got myself covered and that I'm prepared. That said, I'd prefer not to travel with my placard because losing + replacing it would be a pain.

Any advice on how to "properly" preboard with United would be much appreciated. My husband will be with me to help with getting bags into the bin, etc so I'm not anticipating needing additional help or wheelchair aid at this time. Thank you!
