Using all miles OR 40% miles and pay with Avianca Lifemiles

We will be flying Brisbane to Tokyo return in April 2018.

Have used Lifemiles for Singapore to Brisbane early next year (Singapore Airlines)

The current Avianca Lifemiles offer is appealing, but too early to actually book flights.

Is it better to buy full points (80000 each) now; or buy 40% (32000 each) now and pay more money when I book (approx May next year).

Can anyone tell me how Lifemiles assess the cash component of a points/cash fare?

Thanks

Hi Ian,

I have been advised that if you have 45-55% of required Lifemiles for a redemption, you can top up with cash at 1.5 cents per miles. At 40%, top up costs approx 1.56 cents per mile.

There is a slider when you make redemptions, which tells you your cash outlay depending on how much Lifemiles you want to use for that particular redemption.
