What keeps you awake at night?

Increasingly European airlines are singing from the same hymn sheet when it comes to concerns for the future. Fears of a competitive bloodbath - warned of so graphically by Ryanair's Michael O'Leary - have been overshadowed by the Big Two spectres - the environment and airport charges.
And whether they are low-cost newcomers, charter carriers or mainline giants, it seems that Europe's airlines - and the associations that represent them - are coming to the realisation that doing nothing is not an option and that it is essential they can form a cohesive unit that can at least agree on basic concepts.
To this end, and faced with the prospect of a Europe-wide emissions trading scheme (ETS), they are keen to ensure that the impact of such a scheme on their business is not underestimated.
Regulators, including the European Commission, argue that the impact of an ETS on European airlines will be minimal, as the cost of CO2 allowances will be passed on to passengers. IACA, which represents charter carriers, is anxious that this impact is not minimised from a price sensitivity standpoint.
"The EC must talk to us and not to consultants. We must raise the issue above the threshold of a technical argument," IACA insists, adding that the design of any ETS must be "fair, transparent, non-discriminatory and workable for all airlines, including smaller entities".
