Upgrading your Etihad flight is a great way to elevate your travel experience, with options available to move from Economy to Business or from Business to First Class. Etihad offers several convenient methods for upgrades, including bidding through their "Bid Upgrade" program, where you can place an offer and get notified if it's accepted before departure. Members of the Etihad Guest loyalty program can also use accumulated miles to upgrade, while travelers may purchase an upgrade directly through the Etihad app, website, or even at the airport.
