question: their airbus comfy or not? is it the same with their planes to bali, bangkok?

1)If I'm not mistaken, you can still choose and purchase your seat after the computer have assigned you when you check in online. Hot seats are RM25 I think. And they have more leg space. How long is your flight? If it's not very long, normal seats are pretty comfy for me. Depends on your body size and length also. This is mostly up to personal preference.

2)No, I don't think there's any socket to charge any gadgets on AA. If you wanna charge your ipod, you have to use your laptop to do so. Correct me if I'm wrong.

3)Normally it's one hand carry bag max 7kg within the size allowed to fit into the overhead compartments. But most of us do carry a handbag/backpack and another bag. As long as it's not too many hand carry bags then it'll be fine. Remember not to have any sharp objects or liquid in your hand carry. Limited amount of liquid is allowed provided you put it in some ziplock plastic bag they provide.

4)You do not want to get charge for excess baggage at the counter. It'll be very expensive compared to buying in advance. 15kg baggage bought online is RM20 only while 20kg is RM30. For purchasing baggage at the counter, it seems you can only buy up to 15kg which will cost you RM30-50 depending on your destination. Anything extra is consider excess which will be charge RM15-20 per kg I think. (Source: http://www.airasia.com/my/en/flightinfo/supersizesave.html)

5)If I'm not mistaken again, you can only pre-book one meal for each flight, which is mostly not enough for me. So pre-booking meals is just to save some money but I'll end up buying more food on board the plane anyways.

Where are you flying too? Have an enjoyable trip!
