Interesting observations. I always expected Late Dec and Jan to be high season and I am usually prepared to pay an additional premium. But at the moment - that premium is ridiculous.
Picking up on a helpful post in another thread (which Mattg kindly contributed to), I was looking at picking up a good value from BKK to CDG in Jan. I also found a slighly small expensive option out of JKT.
However, getting to BKK and or JKT (or even trying to get to any other close enough Asian airport) in Dec and Jan is ridiculous and well above what might be considered to be the usual premium. Circa $3k to Jakarta. Circa $3.5k to BKK (and thats on Air Asia) or $4.8k on QF. Well over the odds for me (unfortunately for me but if the Airlines are getting people to pay it then I suppose it works well for them?)
Query is, if some of the observations above are true, whether they are, in fact, getting people to pay these fares?
