An airfares question. Looking at airfares from Melbourne to Thailand yesterday. Why would Thai Airways fares (Melbourne - Bangkok - Melbourne) for next month, still high season in Thailand, be approx $950 in February, then in June, low season for Thailand, be around $1300+ climbing to $1900+ in July? Advise used to be to book early, but fares can hardly rise further. I paid $1300 to go in June last year, and the plane was full in both directions. Does the fact that it's high season mid year in Europe impact fares to SEA from Australia? Other airlines are similarly high and low in the same months. Thinking of holding off booking till a month before I travel in the hope that fares may drop (given the low fare for next month), but don't recall spare seats in June and July of last year on the same route. Hoping someone might be able to provide an answer or some insight.
