How to Upgrade EVA Air Seats?

Seat upgrade is one of the ways to enhance your onboard experience on EVA Air. Suppose you have booked an Economy cabin and changed your mind to travel in the main cabin. In that case, you have the opportunity to upgrade to the next higher cabin, such as Premium Economy or Business Class. To do that, you have to upgrade your seat. The seat upgrade process is easy, and the best way to do that on EVA Air is by using Miles. Here on this page, you will find everything essential for EVA Air seat upgrade, including the types of seat upgrades which EVA Air offers and associated information. So, without any further delay, let's jump to the process.

EVA Air Seat Upgrade Options and Their Process.

The airlines generally allow travellers to upgrade their seats in two ways: EvaBidDeal and Award upgrade. Both ways have their own procedure and eligibility criteria. 

1. EVABidDeal:

Under this seat upgrade option, you can participate in a bidding process and have a chance to get a seat upgrade at your own price. To participate in the bidding, there is no direct method open to everyone. Only eligible EVA Air travellers receive an invitation via email 7 days before their flight departs, containing a link that navigates directly to the EVA Air bid system. It allows you to make as many bids as you can up to 50 hours before departure. After that, bidding is closed, and you wait for confirmation.

  • Go to the EVABidDeal page on the official EVA Air site.
  • Click on the "I'm Interested" button to check whether you are eligible for the bid upgrade.
  • Place your bid if you are eligible and receive the bidding invitation in your email.
  • Provide your credit card details and wait until your bid is selected by the airline.
  • You can expect to receive a confirmation within 48 hours of departure, provided you are fortunate, and EVA Air selects your bid.
  • Enjoy travelling in the higher cabin class and its services. 

2. Award Upgrade:

Another way to help you get a seat upgrade on EVA Air using your frequent flyer miles. You can purchase the seat upgrade to move from one cabin to a higher one and enhance your flight experience simply by following the steps below. You will be required to be a member of the EVA Air loyalty program, Infinity MileageLands, and log in with your membership account. Ensure that you have enough miles for the upgrade. 

  • Apply for the award upgrade on the EVA Air official site if you have booked a flight and a ticket has been issued.
  • Enter your Infinity MileageLands Number, Email address, or Username to sign in to your account.
  • Choose your earned miles, or if you have an electronic upgrade certificate.
  • Follow the screen steps to upgrade your seat in the class of interest. 
  • Pay using miles or an Electronic Upgrade Certificate, and the system will automatically deduct the required amount of miles or use the Electronic Upgrade Certificate.
  • Wait until you see a confirmation on your screen regarding your seat upgrade.
