Why Converting JAL Miles to ZIPAIR Points Is a Bad Deal

By Bryce Casson, Founder · Cardocrat · Updated June 2026
The short answer: Japan Airlines lets you convert JAL miles to ZIPAIR points at up to 1 to 1.5, which sounds like a bonus until you realize each ZIPAIR point is worth one yen, not one cent or one dollar. That makes the conversion worth only about a cent per JAL mile, a fraction of what JAL miles fetch on award flights, so it is one of the worst things you can do with them.

The conversion that looks better than it is

Through JAL Mileage Bank, you can convert JAL miles into ZIPAIR points, the currency of JAL low-cost subsidiary ZIPAIR, at a rate of 1 to 1.5 when you exchange more than 10,000 miles, or 1 to 1 below that, in increments of 3,000, 5,000, or 10,000 miles. A 1.5x multiplier looks like free value, the kind of ratio that normally signals a good deal. The problem is hidden in the unit. See transferable points.

Why the yen peg guts the value

Each ZIPAIR point is worth exactly one Japanese yen toward a ZIPAIR ticket, and a yen is a small fraction of a cent. So 10,000 JAL miles convert to 15,000 ZIPAIR points, which equals 15,000 yen, roughly 100 US dollars at a typical exchange rate, or about one cent per JAL mile. The 1.5 ratio is denominated in yen, so it never escapes the fact that the underlying currency is tiny. The big multiplier just offsets a near-worthless unit. See what points are worth.

What JAL miles are really worth

Redeemed properly, for JAL or Oneworld award flights, JAL miles are worth several cents each, often three to seven cents or more in JAL business and first class to Japan, some of the best premium cabins in the sky. Converting those miles to ZIPAIR for about a cent each, to fly a budget airline, throws most of their value away. Use JAL miles for premium award flights, not a low-cost-carrier conversion. The only time ZIPAIR makes sense is orphan miles about to expire with no better use. See JAL First guide and worst redemptions.

Frequently asked questions

Should I convert JAL miles to ZIPAIR points?
Almost never. The 1-to-1.5 ratio looks good, but each ZIPAIR point is worth only one yen, so the conversion nets about a cent per JAL mile, far below the several cents JAL miles return on award flights.
What is a ZIPAIR point worth?
One Japanese yen toward a ZIPAIR ticket, which is a small fraction of a cent. So even at the 1-to-1.5 conversion, 10,000 JAL miles become 15,000 yen of value, roughly 100 US dollars, or about a cent per JAL mile.
Why is the JAL to ZIPAIR ratio misleading?
Because the 1.5 multiplier is in yen, not cents or dollars. A favorable-looking ratio cannot rescue a currency whose unit is worth a fraction of a cent, so the conversion still lands near the floor value.
What is the best use of JAL miles?
JAL and Oneworld award flights, especially JAL business and first class to Japan, where miles can be worth three to seven cents or more each. That is many times what the ZIPAIR conversion delivers.
