I happen to have miles in a few airline programmes and almost all of them are about to expire.
JP miles: 40,000
BA Avios: 30,100
AA: 10,000
Citibank Premiermiles: 40,000

I need a flight from BOM-NYC (JKF preferably)

Could you guys suggest me ways to redeem these miles. If I'm lacking a few miles I'm ready to buy the difference or I'll top it up with Citibank miles.
Any suggestions would be helpful.

are you looking to redeem in economy or business????

I'd like the first leg to be premium economy or business. For the rest economy shall do.

How about BOM-BRU-LHR-JFK?

BOM - BRU on 9W in business class, overnight flight in fully-flat bed.
BRU - LHR next morning on BA in economy.
LHR - JFK same morning on AA in economy. Daytime non-stop flight so economy won't be too bad.

BOM-BRU on 9W in business will require 54000 JP miles. You will need to transfer 28000 of CitiPM miles to 9W (2:1 ratio).

BRU-LHR-JFK on BA+AA in economy will require 24000 Avios. Use the rest of your Avios on short hops within US.

AA miles you can keep active by just crediting a flight every 18 months.


OR

BOM-LHR on BA Premium Economy for 32500 Avios. BA fuel surcharges might be ridiculous on its own metal though and you will need to transfer some CitiPM miles to top off Avios.
LHR-JFK on AA economy again using 35000 JP miles.

Let us know what you eventually do !

not anymore....those are the old rates....now its 85k miles....

Damn I'm feeling old
Thanks Keyser !

OP - You can also try BOM-NRT on ANA Biz using JP miles and then NRT-JFK on JL economy via Avios..
