Can I bring 2 luggage?

I'm flying from New Zealand to Philippines. I got an 8 hour layover in Singapore, and I'm on Economy Class with Singapore Airlines. I never done bringing 2 checked-in luggage. I'm wondering if there's an extra charge with that without over weighing the limit.

Why are crying infants allowed on planes?

I love flying but I absolutely HATE when I have to be seated near someone with their infant who won't shut up. The worst part is the parent does nothing at all to soothe the kid! Read him/her a story, rock to sleep, or put a pacifier in its mouth. People like that are so inconsiderate. I feel airlines should better policies about this. This is so disturbing to the other 100+ people who wanna get some sleep for their long flight! Anyone agree?

Using Amex Points to Travel?

So I've been using Amex Gold Card for some time now, I have accumulated a little over 200k points. I know that the best way to get the best value out of them is to Transfer them to loyalty program for an airline. So I've been wanting to travel from LAX to Lebanon. However, I just feel like I'm not getting the best value after checking the net ammount of points needed to travel through etihad airlines. I was wondering if there's another option I can look at.
