From Doha to Abu Dhabi is a 45 minute flight. Boarding was a bit chaotic but mainly late (and thus so was arrival). The flight being so short, creates a challenge for the (polite and courteous) crew: serve a sandwich and clear up afterwards in the short time. It was a race and the last trolley went back in storage no more than 1 minute before touchdown.
Other than that: this flight is a fancy bus ride.
