On the same subject, I wish to highlight that there is a discrepancy in the Terms & Conditions posted on AirAsia’s official site and on the booking confirmation Mr. X had received. In the former under Clause 8.5 states “Guests may not use the unused Checked Baggage weight and pieces of other guests unless traveling on the same Itinerary”, whilst the same clause in the latter states, “Sharing of baggage allowances with other guests is not allowed, even between parties traveling on the same Itinerary”.
