Last summer, we booked flights from Heathrow-Shannon (Ireland)- New York for this April, through Aer Lingus.
Got to the airport, discovered that the Shannon-New York part of the flight had been moved by Aer Lingus exactly 24 hours, so instead of both flights being on the Sunday, the second flight was on the Monday. Aer Lingus ticket desk discovered that we hadn't been sent two emails we should have been sent, but couldn't tell what the emails would have said - we assume that at least one of these emails should have been the formal notification of the schedule change, hopefully with info on our rights re cancelling or re-booking more convenient flights. They put us up the airport hotel with dinner and breakfast all included.
Also discovered that Aer Lingus HAD sent us an email in December 2018, with the subject "Aer Lingus confirmation" and heading in the email "Booking confirmation" and saying "Thank you for booking your flights with Aer Lingus. This is your booking confirmation. Please check your passport and visa information before travel etc etc".
The changed flight date was in fact half way down that email in the travel itinerary, but because of the subject and intro sentences, DH didn't notice. Neither of us realised that an airline could change your schedule by a whole day - a few hours maybe, but not 24 hours.
We therefore missed a whole day of our holiday, and lost the money we'd paid for an non-refundable hotel booking for the first night. It seems outrageous that a company can change half of a journey (booked as one journey) by such a significant amount of time, but not properly notify the traveller - indeed, they sent a really misleading "booking confirmation" which really implied that they were....confirming our booking, not significantly changing it.
We have complained to Aer Lingus, who say that because of that email in December, they did notify us and therefore we have no complaint. We tried the Civil Aviation Authority who say that this isn't within their scope. We tried claiming the hotel booking money from our travel insurance, who say that it doesn't cover changes to the schedule made before departing.
Clearly we should have read the "booking confirmation" email sent in December 2018 much more closely, and we have learnt our lesson. But it seems ridiculous that Aer Lingus can send such a misleading email when they are changing the terms of our booking so much.
Help! Any ideas what we can do further?
