Good news and bad news.
The bad news is that Aer Lingus have announced their programme for next summer and it just contains Heathrow, Amsterdam , Dubrovnik, Faro, Lanzarote, Malaga and Palma. Most notable is that Paris is not there, but also Barcelona, Lisbon, Tenerife and Alicante are gone (plus a couple [Munich and Nice] that were announced pre-Covid, but never operated). Paris is perhaps a lot more marginal than the cash cow it was, with Air France going 2x daily to CDG and Vueling 2x weekly to Orly. The Barcelona area and Tenerife will still have Ryanair service.
The good news is that Ryanair will go 2x daily to Manchester. That is a major capacity increase and a useful frequency. The only downside is that there won't be hub connections, but Manchester was always the least used of the hub options from Cork anyway.
