I was on a MAAS fare several years ago to PER from SYD due to a death in the family. A OMGO'clock flight, and the CSM came and introduced herself and apologised for my loss. Made it clear that if there was anything they could do just ask. I had not slept in a few days and said 'i don't suppose I could sit in J' (it was empty, not a seat taken) and was told "well i'm sorry we have no catering but you're more than welcome to sit there". I was ushered up, curtains closed, and all the window shades closed for me to rest. They had some of the J 'Mana from Heaven' cakes/cookies, and they plied me with these.
Simply an amazing flight, and it was a very very surreal experience being the only one in J on a 738. Was like my own private jet if that counts, even if the circumstances that had me sitting there were not the nicest.
