Million Mile Secrets reader, Matt, commented:
Is there a way to get a coach flight with miles and then use cash or miles to upgrade to Economy Plus?
Great question, Matt!
Each airline has different rules for upgrading your seat on an award flight.
In many cases, you can pay cash to upgrade at the time you book your flight. Or you’ll have the option to upgrade when you check-in.
And some airlines allow you to use miles or points to upgrade to a more comfortable extra legroom seat on a coach award flight.
For Coach Award Flights, Sometimes You Can Use More Miles or Pay Cash to Get a Better Economy Plus Seat. With Certain Airlines, This Means Free Drinks & Snacks!
I’ll explain the upgrade policy on coach award tickets for Alaska Airlines, American Airlines, Delta, JetBlue, and United Airlines.
