30 min before departure

I found out yesterday that my flight duration is 3 hr 55 minute while the normal flight duration is only 3 hr 15-30 minutes. So what happen to the 1/2 r in the air?
I arrived at the airport. I found out that the counter is in Row E. I went to row E and I could only see counters for Thai, DragonAir and Korean airlines. I walk past row F when I walked back to the computer screen and confirmed it is in Row E. Walking through the Row E again, there were 2 or 3 counters of the words "ValuAir (Chinese Names)" in white which is not the company colour... After I check in, I received this boarding pass printed as a "DragonAir boarding pass"; I got a sticker of DragonAir's but only striked off with handwritten words "VA". That's it...
I'll keep my finger crosses.
