Couple questions for you experts,

I will be flying next month LAX-SIN in economy,

1.) Does each economy seat come with ipod connection outlet from which I can play movies on the personal tv in front of me (streaming from ipod) or just listen to music?

2.)Are snacks included free of charge? if so, what are some examples of items i can ask for?

3.) how comfortable are the seats for sleeping? do you recommend a pillow rest?

thanks ))
