End of the Euro?
I think that France and Germany will fight to keep the Euro come what may, the biggest problem is the politics in Germany of bailing out Greece, few think that the Greek government can deliver the level of cuts being asked for by the ECB IMF and so on and Greece will default, its only when, with Greece out of the Euro the focus will then shift to the remaining members of the PIGS group, who should never have been allowed to join the Euro under the Euro's own rules.
If the PIGS were outed from the Euro then inbound tourism would flourish (other than Ireland, due the weather) to those countries by virtue of a strengthening of the Euro and a devaluation of the PIGS own money.
The problem for airlines is that many countries would be tempted to play the protectionist card and that would hurt pan European airlines like Ryanair who rely on regional handouts to subsidise routes that would not be viable without such handouts.
What places like Tours loose, NCE will gain, ditto Granada v Malaga and many many airports across European have only one volume carrier FR, whilst it is true that FR have grown the market, that is now being reversed across many parts of Europe, everyone has been to Prague and the very long list of none destinations that 9.99 fares made attractive, it was for this reason that FR moved on mass into FAO,AGP,ALC,PMI,BCN and the like over the last few years, but the deals at these airports will not last, nor will FR huge cost advantage as aircraft become older and warranty and delivery deals expire. The loss of regional handouts and increasing costs is a toxic mix for FR that will in all probability force a change to its business policy in order to retain customers in what is now a mature market.
