Would anyone have advice as to which of the airline currencies are most valuable as far as point redemptions and which current sign up bonus offer is most worth signing up for?
New Aeroplan (Chase) offering 70,000 ($95 AF)
American Aviator Business (Barclay) offering 70,000 Miles ($95 AF)
Hawaiian Business (Barclay) offering 80,000 (AF waived)
Alaska Business card (BoA) offering 70,000 ($75 AF)
United business 75,000 - I won't spend 20k for the 150,000 (99 AF)
Any input would be greatly appreciated.
