I am looking at ORD-LIM between Oct-Dec '07 for 7 days. Are there any options besides the AB6 from MIA? I want to upgrade from ECON, but not on the AB6. Also, I'm looking to stay around the $589 that seems to be the best rate for this flight.

Also, if my only options are AB6 or 757, would you rather have the extra 1.5" of width in first on the 757, or the extra 1" of pitch on the AB6, but only 19.5" of width?

Thank You
