I have been planning for a trip to Korea for many months. This would be a great opportunity, actually.
Air Asia, the low cost Malaysia airlines is having another awesome promotion for the next quarter's travel planning. This promotion runs until 2nd June 2013 for those traveling between 1 June to 30 September 2013. Obviously this promotion is mainly for the summer holiday coming up soon.
For a budget airlines, usually promotion price will be offered way, way, way much earlier than the season itself. However, believe it or not, Air Asia is actually giving an almost last minute opportunity for you to buy the ticket at a very low rates. Plus, the price is all inclusive - so there is no need to fear for the hidden cost.
Just in case you have no clue of what to do in Korea (aside from KPop stuff), why not check out this website by Tourism Korea - Korea be Inspired. Here you will have the chance to check out places and things to do in Korea as well as customize your trip.
So, why wait? Go and start booking on the official Air Asia website.
PS. For those who are skeptical of this too-good-to-be-true offer, recently I actually flew with Air Asia to Indonesia at a very cheap price (4 persons, all inclusive, return flight only at US$200).
