I am planning a trip in the future for me and my mom in Business class since she is disabled and needs comfy seats. I have been with Citi Addvantage for a while and have racked up miles. I do see the bonus miles offer you can buy online and the mileage require to travel from NYC-MNL is 140k via JAL.

Is this a good airlines for traveling business class?
is 140k the amount or its too much? 120k was the amount I redeemed when I would travel years ago via Star Alliance.from USA-MNL in business class.

Also the amount 140k sums up to is 2700 plus tax, whereas prices for NYC-MNL in biz is around 3K+.

is this the best deal for us in your opinion?

Am I also missing any promotions/deals or ways/tactics/tricks to take advantage of my AAdvantage membership to get an Elite status. (I don't travel much with AA) and only fly domestic with different carriers once in a while.. Unless anyone has suggestions like buying myself to get elite status to benefit in a business class seat from NY-MNL with the 140k miles?

Sorry if my questions is confusing. I just want to save in anyway possible, period. Thank you all for any tips.
