Take today’s 40% off promotion as an example: buy 24,000 miles or more and get 40% off
Cost comparison
- Priced in US dollars, 24,000 miles cost $439.2
- Change the little globe in the top-right corner to a eurozone country and price in euros, and 24,000 miles cost €360
Today’s euro–US dollar rate is 1.09, so 360 × 1.09 / 439.2 ≈ 89.3%
This little trick can save us about another 10%
📚 Recap
Bought in US dollars, the unpromoted cost is 3.05 cpp USD; bought in euros, the unpromoted cost is 2.5 cpp EUR.
The breakeven is 1.22, so you only need to look at the euro–US dollar rate:
- If it is above 1.22, buying in US dollars is cheaper
- If it is below 1.22, buying in euros is cheaper
