The disabled support offering varies between airlines. You need to check what support is available. Without making a point, this should have been checked before booking a ticket just in case it is virtually non-existent. As you are quoting a 14 hour flight it is possible that you are travelling from the UK. If you are, and you have booked British Airways you will be relieved (no pun intended) that long haul aircraft all carry an on board special wheelchair. However, you need to have advised BA through their website about the level of disabled support you need. If you do register for disabled support then you can choose your seat for free, which means being able to pick an aisle seat close to the toilets. My advice is that you search the website of whichever airline you are travelling on to see what their offering is as a matter of urgency to maximise whatever support is available.
