Seriously? If true, that comes as a massive surprise, I can't imagine why... NCL-DUB-NCL has had consistent double figure growth for a long while now and EI has increased service to the current 16 weekly.
I'd have thought they'd have reduced to 11/12 weekly first before dropping so massively, and if they really aren't offering any TATL connections, then what even is the point? I'd really believe they're deliberately trying to sacrifice the route if they aren't offering TATL connections. Even if this is only seasonal, there's a lot of demand over Thanksgiving/Christmas/New Year that they'll be losing out on.
I sincerely hope that this is not true... And if it is... Why did BA/IAG even bother buying EI? They're dropping UK domestics left, right and centre
