How to book it

  1. LifeMiles books on lifemiles.com: sign in there, search MIA to ORD in business class on a date with space, and pay in miles with the cash on top (from $6).

MilesZone finds the seat; it does not book it or take payment.

Get told the moment a MIA → ORD seat opens.

We re-check that exact seat seconds before the email leaves, so what you open is still there.

Email only. Searching this route stays free for departures in the next 60 days.
