Need to request an upgrade to a higher fare class? The airline considers fare upgrades as a voluntary change to your flight. To request an upgrade, simply tap on the trip in the app that you're looking to upgrade and select "Contact Us." Be sure to select the "Change my flight" option and follow the steps from there.
Please note that upgrading to Premium Economy, Business, or First Class always depends on airline's seat availability and the type of fare that you currently have for your booking.
Using Frequent Flyer Miles to Upgrade
Unfortunately, as an online travel agency, we cannot accept frequent flyer miles to process an upgrade on our end. These must be exchanged directly with the airline you have an account with or with your credit card company.
