Digging up an old thread as this has finally happened to me yesterday SYD-MEL. (Also mentioned in the 3rd row VA thread, but this is the director's cut).
+1 in 5A
I was in 5B
POS in 5C
When we got to our seats during priority seats, we saw a small handbag on the floor under the seat in front of 5C. We initially thought it was an unattended bag as there was no one in 5C. A few minutes later, a POS shuffled her way to 5C. I could already smell a foul odour which smelled like vomit. Could be coming from her jumper (don't even know why she's got a jumper on when it's 30C in SYD), mouth, or body. I fortunately had put the armrest down between 5B and 5C because if she had sat down already, I wouldn't know how to get that down. Anyway, she managed to squeeze into the seat, but her upper body was spilling over the armrest and into my space. Then she had to get a seat belt extension from the hostess. I was willing to forgo the armrest, but intruding into my seat? *sigh*
Not long after takeoff, I could hear this loud snoring coming from her. To top it off, her whole left arm was in my seat, so I only had 2/3 of the seat left. Luckily, it was my +1 in 5A, so I lifted the armrest between us. I'm only 60 kg, but she could be x3 or x4
When it was snack time, her table wouldn't open fully due to her size. She ordered an OJ. I was praying she wouldn't spill it.
After the plane reached the terminal, she was still in her seat not moving. It's only when others started moving when she woke up. We looked at each other and she just said, "I have to wait until the end when everyone is gone". In my mind, I was thinking WTF? No apologies, nothing. After about half of the plane has left, she somehow managed to pull herself out of her seat using the seat in front and moved to 5D to let myself and +1 out.
I think this flight qualifies as my worst flight ever and the lowlight of my weekend trip to SYD.
