Loved premium economy
Pros: Great seats and leg space in premium economy.
Cons: We had the staff come to us twice to keep the "noise" down (we were travelling with a 2.5 yrs old). Now we travelled on other legs with Singapore airlines, with the same toddlers and same "noise" levels, but no one came to us to request to keep the noise level down... I am guessing that premium economy has a different (lower) threshold for toddler "noises" !! :)
