How deep the SNN board really is

The table above says where a courier can fly from SNN. This reads the same 37 destinations back for the questions a dispatcher asks second: how much of the board rests on one airline, how much of it runs less than daily, whether the return leg is as thick as the outbound, what the clock here does to a Gulf working day and which of the destinations shut at night, all of it computed on 2026-09-07 from AeroDataBox scheduled route statistics.

• 36of the 37 destinations are flown by one airline
• 27destinations run less than once a day
• 0destinations have four or more departures a day
• 78.4%of the destinations name Ryanair, the largest presence here

Who holds the departures at SNN

Six airlines appear on the SNN board and they do not hold it evenly. Ryanair is on 29 of the 37 destinations, 78.4 per cent of them, and on 29 of those it is the only airline flying the sector. The destinations it appears on carry 19.2 of the 28.7 departures a day this airport files, though other airlines fly some of the same sectors, so read that as reach rather than as a share of the aircraft.

The next largest presence is Aer Lingus on 4 destinations. 3 of the 6 airlines at SNN appear on a single destination each, which is the long tail every airport carries, and none of it is a rebooking option when the sector you need is the one that fell over.

An airport held this tightly is quick to book and slow to recover: with 29 of the 37 destinations on one airline, the second aircraft on an SNN sector is usually another Ryanair aircraft, and when there is not one the desk is looking at another airport rather than another airline. That is why the alternate airports listed above matter more at SNN than the destination count does.

How much of the SNN board is daily

Of the 37 destinations, 10 are flown at least once a day and 27 are not, 3 of them running once a week or less. The median destination on the SNN board is flown 4 times a week.

An average of 0.14 flights a day is the schedule statistic, and it is worth translating it before anything is promised to anybody: SNN to Prague (PRG) is about one a week, so a missed departure there is not a delay of hours, it is the next slot.

The five busiest destinations carry 10.7 of the 28.7 departures a day, 37.3 per cent of the whole board. With 73 per cent of the 37 destinations running less than daily, this is a board that rewards booking the outbound before the collection is confirmed rather than after.

The ten destinations out of SNN where one airline holds the sector and files fewer than seven departures a week, with the weekly figure taken as the average daily rate multiplied by seven rather than as a fixed timetable. 17 further destinations sit in the same position and are listed in the board above.

The way back from SNN

The desk holds the return direction for 28 of the 37 destinations, and a courier plans the way back on those figures rather than on the outbound. On one of them the return into SNN runs thinner than the outbound by more than a quarter. The widest gap is Roma (CIA) at 0.29 out a day against 0.14 back.

It runs the other way as well: Wrocław (WRO) files 0.86 a day back into SNN against 0.57 outbound, which is the shape that strands a courier at this end rather than at the far end.

The clock at SNN

SNN keeps Europe/Dublin time, three hours behind Dubai in summer and four hours behind in winter, because the clock here moves and the Gulf clock does not.

When it is 09:00 on a Dubai working morning it is 06:00 at SNN, so a nine to six day at each end overlaps for six hours. A customs question raised in the last three hours of the Dubai afternoon reaches nobody at SNN until the next morning, which is the practical limit on a same day instruction here.

The night at SNN

3 of the destinations from here carry a documented night restriction of their own, which is a departure time question at this end rather than an arrival problem at the other.

Into London (LHR) the door shuts at 23:30 local, so the last departure from SNN that lands inside it leaves around 22:08, on a modelled block of 1h 22m. Into Paris (CDG) the door shuts at 00:00 local, so the last departure from SNN that lands inside it leaves around 21:21, on a modelled block of 1h 39m. Into Frankfurt-am-Main (FRA) the door shuts at 23:00 local, so the last departure from SNN that lands inside it leaves around 19:55, on a modelled block of 2h 05m. Those three departure times out of SNN are worked backwards from the published window with the block time model this site uses everywhere, 720 to 880 km an hour by sector length with thirty minutes on the ground, so they are arithmetic rather than a timetable and the desk checks the published departure before it promises the landing.

Where SNN turns up on the rest of this site

The airport also sits behind the Ireland country desk, which sets out the customs practice, the working week and the road legs behind this airport.

Nine courier postings name SNN as the airport a courier here flies from: Cork, Limerick and Galway.

To price a movement rather than read the board, the route calculator opens with SNN already set as the origin, and it works out the flying time, the distance and the delivery hour for any of the 37 destinations above.
