In the booking flow — and later under manage booking — you can add a range of extras, depending on fare and route:
- Seat selection — standard, extra legroom or exit row.
- Checked baggage — extra bags beyond your fare allowance.
- On board — special meals and catering options.
- At the airport — lounge access and priority boarding.
- Assistance — wheelchair / PRM service, unaccompanied-minor support.
Whatever is already included in your fare is clearly marked in the booking step. Paid extras are issued as an EMD (electronic miscellaneous document) in the sim — exactly like a real airline.
