I was so happy to see that finally we can fly pax missions with the Airbuses, and I’ve bought a couple of them, but on my first mission from EGCC to LEPA with an A321 the passengers never embarked 
After loading catering and baggage, the passengers percentage stayed at 0% forever. So mission never started.
Also I cannot understand why airliner missions cannot start in cold & dark. Other missions do. This stoles half of the inmersion. We already know how to awake these airplanes. Let us do it.
