Why buy more miles to a devalued frequent Flyer program, now if Continental has this promo.. I'd scoop it up.. Example: Business class seat award
For me:
Ewr to AMS to BOM on Delta Skymiles = a minimum of 330k miles on saver awards
Where as Continental EWR to BOM = 120K on saver award readily avail.
Delta would need to offer 300% bonus to win my business back..
