What's a good carry on?

I'm currently looking for a carry on for my upcoming travel. It needs to be affordable and lightweight. I have been using an old duffel bag but I'm tired of carrying it around the airport. The only problem is that I have trouble lifting things to put it in the overhead compartment, which has deferred me from purchasing a rolling carry on since I hear they often weigh more.

What can I do in my 3 hr 10 min layover at narita airport?

I will be going to Hong Kong on may 23 and will be laying over at narita for 3 hr and 10 min. I will arrive at 3:20pm and depart at 6:30. I realize from other posts that I can't go out and explore narita due to lack of time therefore what can I do specifically to burn the time? What restaurants should I check out?

I have a CFO sticker on my old passport, got it when I was 11 y/o. Now I'm 2 months away from being 18, what should I do?

I have read that once the Commision on Filipino Overseas sticker/certificate is issued, its validity is forever. However when I got mine, I was 11 years old and went to Manila for the seminar only to be told that it wasn't required for me yet. I got my sticker in the airport the day of our departure. Now, that sticker is in my old passport and I'm flying again with a different visa (I've flown to and from my parents place on tourist visas before). My concern is now that I'm near the legal age, is there a need for me to go to the seminar and get a new or transfer that CFO sticker to my present passport? And what are the requirements, if ever?

Any help would be appreciated. We re on the process of finalizing everything.

Does British Airways Food Choices?

Does British Airways offer you a choice of food for their standard meals while you are on the plane? Not the diet specific or up charged meals.
