Is priority luggage delivery also a benefit of the Altitude card? Got priority bag tags at Brussels Airport, thought this was because of the check-in at the Biz counter but also when using the self check-in at Vienna on the way back the bag tag showed priority. (and surprisingly our suitcase came even out among the first at Brussels :-))

On another note, I used the fast track passes in the Mastercard Travel Experiences app for Vienna airport. Comes with some administration, you need to book at least one hour in advance and need to select a specific time slot of 30 minutes. You also need to enter the name and surname of each person you request a pass for.
Wonder why all this is necessary. Will they ever deny passes if they have 'sold' too many for a certain time slot?
We arrived 10 minutes too early but our passes worked. I scanned my wife's fast pass QR code with my boarding pass, and vice versa and this worked as well. So not sure if they check any of the information you provided.
