Traveling with disabled person

I am traveling to Vegas in early June with my girlfriend and her health has gotten worse to where she needs a wheelchair. My question is mostly on how to travel through the airports. Does she arrive in her own wheel chair, check in the chair and then use an airport wheel chair to get to the gate or does she get to stay in her own chair?
If she does get to use her own chair, how do we ensure it will show up in LAS when we arrive?
I wanted to rent her a motorized scooter but she won't use one since she ran over a child in Target.
Thanks for any information you can provide.

Call the airline and tell them you need a wheelchair and they'll have one waiting for you at the curbside check in at least that how it's worked for us at Dulles using United and SW I believe. I had to do it a couple times and there was never a problem, they'll wheel her right to the airplane door if needed. If she can walk some, they'll drop you guys at the gate and take off. If she's completely immobile I'm not sure how that works, I just had a problem walking long distances when I first got out of the hospital.

I would try and get her to reconsider the scooter idea, pushing a wheelchair around Vegas is going to be extremely hard after awhile. It's the only way to get around Vegas if one has any problem walking at all, I still get one even though I'm pretty mobile but walking any kind of distance is extremely painful. The rental company drops it off at the front desk/concierge, it's super convenient, and simple.

My concern would be checking your chair as baggage. What happens if it is mis-routed? I'd think gate check would be best, but call the airline and talk to someone.

I would rent an Everest and Jennings chair when you get there.
They can deliver it to your hotel. Done that twice!
A scooter would be much better: A SLOW one.
Inside the airports is no problem. Those are pushers only: NO self propelling,usually.

I was just tall enough to shoot craps from my 'chair.
When we went to a show in Reno,a REALLY BIG security guy lifted me and my chair right to the front row!!!!!
I was 150 pounds back then.

One of the bad things about 'Vegas sidewalks is the built in camber that tends to roll you towards the curb
and it makes one work hard to keep a straight line.

The other problem that I had was extreme build up of static electricity while on the casino floors.
I could throw a spark 1/4". I learned to ground out myself with a half dollar on the machines.

I wore out a pair of gloves,getting around and it was hard work. The carpets are thick and takes extra horsepower to wheel around. Don't get a 'chair with "Slicks".

I'll get one of those,next time!

I used to go to Vegas all the time with a friend that needed a wheelchair. Arrive very early at the airport, three hours before your flight. This will give security a lot of time to give it the once over twice. We were able to keep his chair with him all the way to the doorway of the plane. We had the front row seats and I was able to help him to the seat once the chair was taken away. They took the chair right down the steps and put in cargo and soon as he was seated.

When the plane landed, we had to wait for everyone to get off. That's when they brought the chair back to us and we got off.

I used to joke with him that was the only reason I took him with me. Front row seats and we were the first ones to board.

Things may have changed so call the airline to be 100% sure.

There are also motorized wheelchairs available for rent in Vegas.
Might be a safer option for her.

Perhaps she wasn't accustomed to the scooter when she ran over the child.
If set on "turtle" mode instead of "rabbit" mode, it can't go terribly fast.
The operator's hands control the stop and go. Takes a little practice, but not much.

Rent an "Airline Approved" travel scooter. You are allowed to take it right up to the gate. They will then store it in a preferred section of the cargo hold and take it off of the airplane and bring it to the person at the destination. If help is needed from giving up the scooter to getting to the seat, there is a special thin wheel chair at each gate, whereby the person can be taken right to their seat.

He said she doesn't want to use a motorized chair.

Yeah.... We all missed the point. Her choice.
OK,how about a carbon fiber/composite chair with wheelie bars?
Very light weight and super-easy to wheel around.
Gotta do some research on that unit,first.
I'll guess they are $1,000 to buy.
