I recently calculated the conversion rate between euros and miles for a flight from Hannover to Singapore on November 15th. Here are the details:

• For the Basic ticket, which costs 3,818 euros and requires 110,376 miles, the conversion rate is approximately 0.034591 euros per mile. This means that 1 euro is equivalent to about 28.91 miles.
• For the Flex ticket, which costs 4,060 euros and requires 131,976 miles, the conversion rate is approximately 0.030763 euros per mile. This means that 1 euro is equivalent to about 32.51 miles.

Have I understood well?
