What assistance is available for visually impaired travelers arriving in Bangkok?

Hi to one and all, I shall try to briefly explain my situation. I am totally blind and I’m travelling to Bangkok on the eighth and arriving in Bangkok on the ninth from Manchester and changing at Amsterdam on the way . The issue that I’m having is that the website is not very accessible I’ve tried using a mobile phone and laptop because I use a screen reader which allows me to know what is on the screen however, the drop-down menus are not being displayed or spoken and when I have to search for certain things such as the different categories that are listed it doesn’t let me activate anything. so to give you a scenario, if I’m trying to choose my preferred accommodation to where I will stay I can jump into the search box but then it won’t actually find the results.  What is people’s suggestions? Should I just arrive at the airport and see if the airline can help me with it or just hope the best. I do understand that I have to fill this form in online 72 hours before I leave.  Thanks a lot
