Airline miles value: Domestic vs. international
If you’re trying to maximize the value of your miles, you may be better off booking international travel over domestic with some airlines. Among the itineraries we surveyed, international bookings sometimes had a higher mile value than domestic flights.
Alaska Airlines — which has limited international routes — is an exception to this trend, offering a lower value on international flights. Southwest, Delta, American and United‘s international routes offer better value, but JetBlue has the same value no matter where you travel.
| Domestic | International | |
|---|---|---|
| Alaska Airlines | $0.019 | $0.017 |
| JetBlue | $0.013 | $0.013 |
| Southwest Airlines | $0.012 | $0.013 |
| Delta Air Lines | $0.011 | $0.012 |
| American Airlines | $0.010 | $0.015 |
| United Airlines | $0.010 | $0.012 |
| Average | $0.013 | $0.014 |
You should be aware that your miles don’t usually cover taxes and fees, and these taxes can be particularly high for international flights While the specific taxes you’ll have to pay will depend on the country you’re visiting, the highest taxes include air passenger duty, passenger service, airport security charges and passenger facilities charges. You’ll need to determine whether the additional mile value outweighs the taxes for international flights.
Airline miles value by seat class
On average, the value of an airline mile is slightly higher when booking Economy Class versus Business Class. However, this doesn’t hold true for every airline rewards program.
American offers slightly more value for a Business Class fare. On the other hand, JetBlue generally offers the same value for both fare types.
| Economy | Business class | |
|---|---|---|
| Alaska Airlines | $0.019 | $0.018 |
| JetBlue | $0.013 | $0.013 |
| Southwest Airlines | $0.014 | $0.011 |
| Delta Air Lines | $0.012 | $0.011 |
| American Airlines | $0.012 | $0.013 |
| United Airlines | $0.012 | $0.011 |
| Average | $0.014 | $0.013 |
Airline miles value by peak vs. off-peak
While the value of your miles can vary throughout the year, airline miles are often worth more during off-peak seasons than they are during busier ones. With dynamically priced programs, including JetBlue, Southwest, Delta and United, miles were more valuable during off-peak travel times. Meanwhile, Alaska Airlines and American Airlines — which still use charts to price their awards — had better values during peak times, which is good news for those who need more flexibility.
Note that the difference was small across all the airlines in our survey, so you’re likely to get a solid value for your miles regardless of whether you book an award flight during peak or off-peak season.
| Peak | Off-peak | |
|---|---|---|
| Alaska Airlines | $0.019 | $0.017 |
| JetBlue | $0.012 | $0.014 |
| Southwest Airlines | $0.011 | $0.014 |
| Delta Air Lines | $0.011 | $0.012 |
| American Airlines | $0.014 | $0.011 |
| United Airlines | $0.011 | $0.012 |
| Average | $0.013 | $0.013 |
Reward program usability
Mile value isn’t the only thing to take into consideration when determining the best rewards program for you. How easy it is to use your miles and how complicated the rewards program is to navigate also play important factors.
Overall, Southwest offers overall the most usable miles. That’s because it has an easy redemptions and booking experience, as well as good award availability.
JetBlue, on the other hand, had the lowest usability score. In particular, we found that its flight network isn’t as robust, it has no transfer partners and the terms and conditions of its program are particularly dense.
