For the last few days I've been trying to check availability and prices on ba.com by logging in to my account, using the drop down box to select book with money and upgrade with avios, entering the airports, dates, class that I want to upgrade from, tick both ways and then when i hit enter it just takes me to another screen which is blank as below. Its really frustrating. I've cleared cookies, deleted history, tried it on my work laptop and my home laptop and its the same on Chrome and Internet explorer. Any ideas?
