GSM will not be going "breasts up". They have hedged their fuel for most of S08. They lease out the A/C for longhaul over winter which is cash-lucrative. GSM will be losing their B733s and B736s over W08, leaving the A/C as:
5 B738
2 B7NG
3 B763ER
1 B752ER
2 B787s (on order delivery 2010)
I think for S09 GSM will have to have these A/C replaced with other 700s or 800s. The heavily reduced routes for W08 will be operated with:
GLA 4 B738s, 1 B752
EDI 2 B7NGs
ABZ and MME will be W Pattern flights or position down from GLA/EDI.
Spare B738 might be leased out.
SFB will catch up tomorrow, with the B763 not scheduled to operate again until Tues.
The schedule is loose until the SFB flights go daily mid-June.
