That's correct as far as i've heard... the figures don't make sense to me.
Think its time we got over TOM and TCX (and LS) dropping 757's and move on - S15 compared to S14 will be the same for both TOM and TCX, not a decrease and if jet2 replace a 757 with two 737's then that will be a net increase.
Can't remember exactly when TOM dropped the 757's but you can't keep inferring they are decreasing NCL next summer when they aren't - the 738's have been around for atleast a year now
