I always pick my seats when I purchase the tix. You probably still can through their website. Otherwise you may get 5 middle seats in the back ! If going through immigration, I like the 100B seats up front, just behind the 'red seats'. IIWY, I'd just buy the smallest kg checked bag option. Before hand it's cheap. At the airport it sure isn't. Food ? Not a clue. I give it a skip no matter how hungry.
