Well the reason behind for not upgrading the other person is we had a fight and I do not want to travel with her anymore.

Secondly is because I will be flying to Korea after arriving in HKG then i prob wont get to sleep until like another 24hrs later after we arrived in Korea so I thought I might see if its a good deal to upgrade myself for the flight so that I can get some decent sleep!

Thanks for the advice

Also, I asked the lady how many spots left in PE, she advised 2 and there is plenty of seats in the upper class, what do you guys think for myself getting "free upgrade" to upper class?
