We would like to take advantage of 2 for 1 sale for China in 2011. However, not willing to pay in full by July 31 of 2010. Any educated guesses if this sale with low cost air will be offerred later in the year or closer to 2011 travel dates? Also hoping to upgrade to business class with AA frequent flyer miles. Any suggestions. I am afraid we are not too savvy on these matters. Thanks for any help.
