Hi,
I just wanted to provide reassurance that I had this issue too, I could not go to the loo on a plane, even when I was bursting. It didn't stop me travelling but like you, I would restrict flights to 3 hours or less. However, I recently not only went on the plane, but also on a boat! What I found really helpful is watching YouTube videos of plane toilets, listening to the noises and then feeling relaxed whilst watching the videos. (it may sound daft but it really worked) I also book an isle seat so I can try whenever and I found it helped having my partner stood outside the door.
I found the virtual workshop through UKPT a huge help! It is since taking part in the workshop that I have had so much success. The key is to relax and smile every time you go to the loo, even if you don't manage to go, still smile. fake it.
Ann is super helpful too, after speaking with her on the phone, via email and on the workshop you will already feel better.
In the meantime, if you did need to travel further than three hours, take two flights. I took two flights to the canaries. you can even try and go on them and have more opportunity to try.
Good luck! You can overcome it, we are proof!
