We took this flight a few weeks ago, MCT-AUH. Air Serbia crew, complete with black leather gloves!

I was in economy with child#2, seat pitch fairly tight, but otherwise OK, pillow at every seat.

My wife and child#1 were in business, looked OK from where I was sitting

I gather the aircraft operates a rotation BEG-AUH-MCT and back, our MCT-AUH departed over 2h late due to delays on the BEG-AUH sector earlier in the day. EY didn't handle the delay particularly well at MCT, we were sent from the Plaza Premium lounge to the gate area far too early even though the inbound aircraft wasn't anywhere close to landing.

We made our connection at AUH with minutes to spare, after running from T1 to T3. Luckily our departing aircraft had also been delayed on a previous sector.

My wife's verdict was "We're not going via AUH again". She'll get over it.
