Which flights can I upgrade?
If you want to upgrade a journey with multiple flights, you need to place a bid to upgrade each flight individually.
For example, you can place a bid for your outbound flight and opt not to place a bid for your return flight. You can bid different amounts for each flight.
If you don't want to bid to upgrade a flight, just move the slider to the far left to indicate No offer for that flight. Easy!
Please note that flights must be operated by Brussels Airlines to be eligible for an upgrade.
