Just less than a year ago, while travelling on a through-ticketed EI itinerary, I missconnected in DUB, due to a late arriving EI-operated flight.

The ticket desk where I was sent to be reaccommodated told me that "Aer Lingus is a point-to-point low-cost carrier, and they do not guarantee connection".

I insisted that my flights were through ticketed, and that they had an obligation to protect me.

Anyway, it took three hours of negotiations to get rebooked, and despite a promise from the DUB duty manager, I still haven't received the reimbursement of my overnight hotel expenses.

I'll be following it up with the EU in a month or so, when I'll have a bit more time.

Wish I had more cheery experience to share... but frankly, EI isn't so cheery.

If your flight is ontime, though, 70 minutes should be sufficient for the connection.
