It is important to separate the outstanding airline that JetAirways is from the FF program. JetPrivilege has been improving a lot lately. I give it a B+ overall and if they can fix a few things it can easily move into A or A+.

Earning Ability
A. Generous bonuses for premium travel (100% for F and 50% for J) and some incremental bonus for elite travel (Plat and Gold). Strong partnerships with Credit Card companies (but only India based) allowing upgrade vouchers and mileage accrual for spend. Not many other partners with the exception of a few hotels, car rentals, etc.

Partnerships
B+. Not a member of a global alliance. Does have redemption and earnings with several world class airlines. Codeshares with AA among others and that is a big plus for North American pax. QF and Brussels Air are great for other continent travelers.

Elite-Level Program
A. Treats elites well (priority baggage handling, lounge access on the day of travel, early online checkin, etc.). Has a novel concept of dynamic review - which allows you to reach elite status in an acclerated time (similar to challenges with a 6 month review period). Also renewal of elite status requires slightly reduced requirement. Also, a 24 month window is allowed for elite status renewal. Limited lounges outside India (primarily in Brussels hub). Partnership with AA gives access to Admirals club in JFK for Plats (not sure if it is a policy or a personal exception). If they were a member of a global alliance, they would score a A+ here.

Rules & Conditions
B-. Except for dynamic review not very innovative. Not many creative or compelling promotions. Mileage based redemptions. Would be nice to have country or other type of redemptions as well.

Service Support
A. Very help staff but processes and software is limited.

Online Services
B-. Used to C a few years ago. Improved a lot lately. It should get to B+ and A- with improvements to richer search, better international ticketing and award support, etc.
