The lack of headphones impacted our ability to enjoy the entertainment system provided. The fact that my last connection was associated with an "affiliated airline" that did not allow me to retrieve a check in or a boarding pass via the app almost posed a significant issue as the last leg of the flight was overbooked and we were stressed about getting a seat as a result.

  • What airports serve Gatwick to Ireland flights?

    Gatwick International Airport, conveniently situated in the south of England and only a short distance south of London, is the second busiest airport in the UK and services flights to Ireland from Gatwick. Departing from London Gatwick Airport, you can swiftly reach Dublin, situated on the east coast of Ireland, or Shannon, situated on the country's west coast. Dublin Airport is located to the north of Ireland's capital city Dublin, while Shannon Airport is found just northwest of the town of Limerick. With both airports acting as gateways to the rest of Ireland, you can pick your preferred option.

  • Which airlines fly directly from Gatwick to Ireland?

    You can fly directly to Ireland from Gatwick with airlines like British Airways, Ryanair and Aer Lingus. A common choice is to fly directly from Gatwick Airport to Dublin Airport with any of these airlines. You can expect flight durations of between 1h and 1h 30min and over 20 direct departures from Gatwick to Dublin each day. Departures are spread across the morning, afternoon, and evening, so selecting a flight that fits your schedule is easy. If you would like to go to the west coast of Ireland, you may consider the option of a direct flight with Ryanair from Gatwick to Shannon, with a flight duration of less than 1h 30min.

  • What are the stopover options between Gatwick to Ireland?

For example, you could opt to fly to Dublin and then onwards to Cork in the south of Ireland. This may be useful when there are no direct flights available to take you directly to Cork. Another option is to travel from Gatwick to another airport in London and onwards from there, like travelling to London Stansted Airport and from there on to Shannon. You should find that prices remain relatively low, with short stopovers adding only a bit more time to your journey.
