Well I also face flight delayed for almost 3 hours recently on way back from Jakarta to KL. AA should apologise on this matter or provide free snacks to compensate the time loss, frustation and anger of his customer.
They can accuse people of creating problem when miss out the boarding time, but when when it come to their own inefficiency (flight delay), why keep silent about it. I know its a cheap fare but customer service is about pleasing customer, not frustating them.
I may take AA again for its fares but MAS still No. 1 in customer service and they have higher expectation rather than 'o.k lah' pay less why making so much noise type of AA.

Change it to 25kg in the Airasia Booking Online or you just carry one beg into the plane and another one put into luggage.
