Jet2s 737s from NCL do 2, 3 rotations a day maximum!!
The 757s have lots of down time (just as well at mo) as 1 operates MJV everyday and the KRK mon and fri
757 number 2 operates the PMI daily with the odd AGP thrown in.
Wed only 1 757 flies but think the PMI which was on 737 on a wed may have been put on to 757 for peak season, so they have a very relaxed flying programme.
The 767 rumour has been going round for ages but not as strongly as now
had heard it was Ex XL.com 767s cummin tho, along with 2 more 757s for next summer.
I had heard that the powers above were sick of delays and are now seriously looking into 733 replacements with either airbus A319/320 or 737-700
