Terminals & connections
Dublin Airport has 2 terminals. Transfer system: Single connections area under one roof; Terminal 1 and Terminal 2 are a 5-minute walk apart. OAG airport standard is a flat 45 minutes for every sector. Aer Lingus files (and publishes) higher route-specific minimums at Terminal 2 that the OAG data confirms to the minute. At Dublin 'domestic' means within Ireland, so Europe-to-US and Europe-to-Europe connections are both international-to-international. US Preclearance lets passengers arrive in the US as domestic passengers.

1 airline: Ryanair
Ryanair is point-to-point and offers no connections; a T1 connection is a self-connect.
Terminal 2
5 airlines: Aer Lingus, American Airlines, Delta Air Lines, United Airlines, JetBlue
