Here and there on the news over the past few days they have held interviews with people who are experts in interpreting consumer law - consumers rights body people, folk from Which? etc.
They have all categorically stated - no ifs, no buts - that if a customer's contracted flight is delayed for whatever reason airliners/travel operators have to provide alternative accomodation and food commensurate with that delay. Airliners and tour operators can not refuse to do so or refuse to compensate. That is a breach of the law. If they don't provide it, and a customer ends up shelling out themselves, then they have to compensate a customer to full value of whatever they have spent. Whatever the terms and conditions of sale says, that's the law. It's called European Directive 261 or something.
And there is no limit to it, so if the only accomodation a customer could find was in a 5 star hotel at a grand a night, they have to stump up, which gives airlines/travel companies a clear economic incentive to provide the accomodation themselves or repatriate the customer by some other means.
If the airliner or travel company management don't know how to run their businesses properly and don't like the law, one possible solution would be to sign the businesses over to the workers and workers co-operatives.
This would also stem the tide of the redundancies within the industry.
I'm sure such workers co-operatives would be more than happy to ensure customers are well looked after, as well as ensuring the profits from the businesses are shared out properly amongst the people that do the actual hard work, day in day out at the coal face of the business - cabin crew, engineers, pilots etc.
I realise the chances of such a thing happening are remote of course, given the ideological top down hiearchical dogma that often exists in business leviathans. As history has shown, if such businesses fail or are in danger of doing so, they much prefer selfishly moth-balling their infrastructure so nobody else can use it or benefit from it, until they rust and crumble.
If you don't look after customers, your business is finished. The customer is king, or at least should be treated as such. Plus if you develop a reputation for sharp practice and this spreads then on a wider scale your actually damaging the wider economy. People stop spending when they get treated appallingly by businesses and their consumer rights and protections aren't observed or enforced.
I believe I am correct in saying that this is the first time in recorded history that commercial airliners and travel companies have suffered such a large scale closure of flight space, lasting nearly a week.
For the oldest of the businesses, that's literally decades they've had to save and build up their reserves in self-insurance for such a rainy day, or in this instance, an ashy week! If they don't have sufficient reserves because they've been distributing them to shareholders and fat cats at the top for decades, that is hardly the passengers fault. They shouldn't have to pay for the airliners and travel companies financial practices and lack of foresight.
