Just saw this after I booked with Jetstar 2 for 1 and it turned our that this one is a bit better in value after all the add-ons. For example I paid $1465 for 2 people ADL-NRT return with two 20kg luggages and one 15kg, no meals only some inflight voucher and entertainment and only some seat selections.
This offer includes changing travel dates, food service, entertainment,seat selection and don't need to buy the "bundle" from $1516.
My first time travelling to Japan but next time definitely going to check Cathay Pacific's promo before booking.
Soooo sorry for myself now:(
"Seoul", not "Soul"
