How Many Miles Do You Need for a Free Flight on United?
If you have been traveling with United Airlines for so long and wondering how many miles you can use from your collection to book a flight without paying, then you must have at least 50,000 miles. These are the average miles you should have, as it also depends on the details of your itinerary, the class, destination, fare type, time of booking, and the membership you hold; everything depends on how many miles will be required.
