There are several ways in which your travelling companions might benefit from your membership when they travel with you.
An Emirates Skywards member of any tier can buy instant upgrade rewards with Skywards Miles at the check-in desk for companions who are travelling with them on the same flight. Silver, Gold and Platinum members can also take advantage of this service on board the aircraft.
Emirates Skywards members who have lounge access can invite guests travelling on the same Emirates flight to join them in the airport lounges. Your entitlement will depend on your tier level. Please see the FAQ on lounge access for more details.
Travelling companions of Platinum members may benefit from priority baggage delivery, subject to availability. Platinum members may nominate another Emirates Skywards member for a complimentary Gold Partner card.
