Hi! It seems that they post only up to about 7-8 months in advance and being that you said they have up until Jan. 2005 right now, that sounds about right. I am referring to the internet. However, I wonder if you try on the phone if they can give you a fare for April? On line, I would say they may not have April 05 listed until August or Sept. Good Luck with your planning. I am sorry I do not have a more specific answer for you.
