I follow the Colombo fares quite closely and a couple of recent interesting trends to note. First KL started to jump into the fray and add some extremely low fares where EY and QR usually covered the bottom rung. But more interestingly I have seen a number of these short term duration sales where the maximum stay has been extended. For these QR fares, there is a relatively long six-month max stay, where are most of the bottom rung fares are two or three months max.
There are actually a number of QR fares to BOS, mostly furring in name between 5, 4, 2 and 1 designation. The "accompanied travel" section of the fare rules seems to indicate that is the minimum number of travelers to get the particular fare. Am I reading that correctly that for the cheapest fare you need five travelers?!
