Best flight - got upgraded to business class on a Cathay flight from HK to Melb. Fell asleep at one point in the comfy seats and I swear when I woke up, the flight attendants put a blanket on me and tucked it around my arms.

Worst flight - flying Caledonian airlines from Toronto to London (Gatwick airport). The food warmer was down so everyone enjoyed a very cold meal. Hot water ran out halfway through due to some technical fault. My parents were quite miffed. Thankfully it's only like 6-7 hour flight.
