Hi guys,
Thanks for all your help. I will try to answer all your questions. I have not made any changes to my browser that I am aware of. The weird thing is, I used to have no trouble typing in three letters and getting the airport code. I tried the pop up blocking thing (I think I did it right) and I had no luck. Everythiing under "scripting" is enabled in my internet options. My hunch is it is a JAVA thing but i don't know what. I also tried using just the airport codes and this did not work.
As I mentioned in my earlier post, if I click on "websaver" then scroll down to "book now" - it works. What is different here? The thing is, the second I use this method as a way of booking, I have to delete the cookies on the site or I cannot get onto it again. Any other suggestions??
Thanks for all your suggestions so far.
