When the original 5 "A" market machines were leased there was an early termination clause written into the last two deals which happened to come up this year. Thus G-ZZZD and G-ZZZE are being stood down at CWL and when I'm next at work I will check in FICO to see which of the two has arrived there first. (No you're thinking logically - it might be 'ZZE!)
The fate of upto 5 later aircraft is in the hands of the market.......
