NSI Yaounde

How deep the NSI board really is

The table above says where a courier can fly from NSI. This reads the same 13 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.

• 10of the 13 destinations are flown by one airline
• 9destinations run less than once a day
• 1destination has four or more departures a day
• 30.8%of the destinations name ASKY, the largest presence here

Who holds the departures at NSI

Nine airlines appear on the NSI board and they do not hold it evenly. ASKY is on 4 of the 13 destinations, 30.8 per cent of them, and on 3 of those it is the only airline flying the sector. The destinations it appears on carry 1.7 of the 14.8 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 Afrijet on 3 destinations. 3 of the 9 airlines at NSI 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.

That is a middling concentration at NSI: one airline on 30.8 per cent of the destinations and the other 69.2 per cent spread across 8 airlines. A cancellation inside the ASKY network is often survivable inside the same booking, but on the 9 destinations ASKY does not touch, a rebooking means moving to a carrier the desk has to check for a through fare first.

How much of the NSI board is daily

Of the 13 destinations, 4 are flown at least once a day and 9 are not, 2 of them running once a week or less. The median destination on the NSI board is flown 5 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: NSI to N'Djamena (NDJ) 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 11 of the 14.8 departures a day, 74.1 per cent of the whole board. More than half of everything that leaves NSI is aimed at those five places, so the depth on the board above is thinner than the destination count suggests, and a hand carry that is not going to one of them is planned around a single departure time.

The seven destinations out of NSI 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.

The way back from NSI

The desk holds the return direction for 10 of the 13 destinations, and a courier plans the way back on those figures rather than on the outbound. On two of them the return into NSI runs thinner than the outbound by more than a quarter. The widest gaps are Paris (CDG) at 1 out a day against 0.57 back and Addis Ababa (ADD) at 1.3 out a day against 0.86 back.

It runs the other way as well: Libreville (LBV) files 1.1 a day back into NSI against 0.57 outbound, which is the shape that strands a courier at this end rather than at the far end.

The clock at NSI

NSI keeps Africa/Douala time, three hours behind Dubai all year.

When it is 09:00 on a Dubai working morning it is 06:00 at NSI, 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 NSI until the next morning, which is the practical limit on a same day instruction here.

The night at NSI

2 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 Brussels (BRU) the door shuts at 23:00 local, so the last departure from NSI that lands inside it leaves around 15:08, on a modelled block of 6h 52m. Into Paris (CDG) the door shuts at 00:00 local, so the last departure from NSI that lands inside it leaves around 16:21, on a modelled block of 6h 39m. Those two departure times out of NSI 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 NSI turns up on the rest of this site

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

To price a movement rather than read the board, the route calculator opens with NSI already set as the origin, and it works out the flying time, the distance and the delivery hour for any of the 13 destinations above.
