Transfer from manual wheelchair into aircraft

My last 4 or 5 flights overseas I wheel near the door of the aircraft and am expected to seat myself at the dolly like carrier on inside of aircraft. The problem is, the ramp leading up to the aircraft differs in height than the aircraft. I have to position my backside as near the dooly as possible then hop up on the dooly. If the ramp and aircreft door were at the same level, things would be much eaiser. To people walking on the plane it matters very little, to me it matters a lot. 

Want others to talk about flying longer distances, another important issue is use of the washrooms

I fly short distances usually twice a year. I always sort with the travel company accessability dept to prebook my seats so I'm at the front of the plane or as near as possible so can get to washroom easy. I'm visually disabled. impaired as well mobility

Most difficult for me is moving onto the dollie and using the washroom. A flight to Hong Kong, I used jar to relieve myself, afterward my partner will take to washroom and empty.
I do the same when I am on my own for my approximately 7 trips to Thailand. As a point of interest even though I find the ladies extremely attractive, I have never been together with a professional. Most of my time is spent wheeling around exploring.

I really love Thailand would love to go back one day soon after my hips and other joints have been fixed.

Transferring from a manual wheelchair into an aircraft involves several steps to ensure a smooth and safe transition for passengers with mobility challenges. Typically, airline staff or ground crew will assist passengers in transferring from their wheelchairs to a special aisle chair designed for narrow airplane aisles. Passengers may need to lift themselves or be assisted by staff, who will then maneuver the aisle chair to the designated seat onboard. Once seated, the passenger's wheelchair will be stowed in the aircraft's cargo hold for the duration of the flight. It's essential for passengers to communicate their needs and preferences to airline personnel beforehand to ensure a comfortable and dignified transfer process.
