Flybar,
Surely the fact that they have a fleet made up of many gas guzzling older planes (733s and 757s) may take its toll now that oil prices are on the rise again and increased general maintenance ?
Even their 738s are pretty old.
Suppose depends on whether they hedged their fuel and if so what at.
Current Brent Crude has risen from below $100 a barrell few months back to $114 a barrell today, with a market forecast of possibly up to $121 by end of year.
Jet 2 remind me slightly of BMI Baby, whos fleet of older 733s and their inability of being able to buy new generation planes probably paid a big part in their demise.
