I pay extra to have that 'privileged' access to a washroom.  I also pay extra because I am tall, have some disability and health issues and appreciate getting on the plane a few minutes early.

I hate the whole cheap flights, cheap service and people who demanded it and then complain when the airlines delivered it and more.  

I can't afford the 'luxury' of the better seats and service, but I wouldn't be able to travel anywhere if they weren't available either.  I make a choice to fly less often, and stay longer to amortize the huge cost.  

It's unfortunate that airlines are serving the lowest common denominator in providing a cheap seat and zero amenities.  I'm just waiting for them to start selling the overhead bin space and install pay-per-poop toilets.  

From the behaviour and attitude of some travellers I have seen, removing the curtains and installing reinforced doors can't come soon enough.  

Enjoy your flight.
