The light-year is a unit of length used to express astronomical distances. It is about 9.5 trillion kilometres or 5.9 trillion miles. As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year (365.25 days). Because it includes the word year, the term light-year is sometimes misinterpreted as a unit of time.

Booking United flights with Air Canada Aeroplan. Since Air Canada, just like United, is a Star Alliance member airline, you can use its Aeroplan miles to book United flights. And since Air Canada is a member of the AMEX Membership Rewards program, you can transfer Membership Rewards points to Aeroplan. The prices for awards with Aeroplan miles are generally pretty close to what youâd pay if you used United MileagePlus miles to book a United flight, although there are some deviations.
