Why change though? Does the EXS flight number signify that it was a dead-leg not carrying any passengers back to its origin, Leeds?

Nothing has changed it has always been EXS as its ICAO code but on your ticket it will show as LS, if you look at FR24 Ryanair show as FR while ADSB it shows as RYR and Easyjet UK either
EZY or U2 and Easy Europe EJU or or U2

It is standard for passenger carriers to have a 3-letter ICAO code for use in the ATC environment and a two-letter IATA code for ticketing.

You can find comprehensive lists online if you are interested.

It does seem that the EXS designator is used for either positioning or deadleg flights.

I read the OP's question as "why might it show LS inbound but EXS outbound on the same app?" In my view, likely to be a software glitch rather than anything more around "loaded inbound, ferry out", "or pax inbound and resort staff out".

But VLC is not a usual Jet2 destination, nor is it a package holiday destination - TUI Belgium are the only non-scheduled carrier to operateinto VLC on a regular basis so Jet2 was a surprsing visitor. This was the reason I posed the question

LBA-VLC was a charter flight for Leeds United FC

A330 on the MAN-ACE route for summer 2023, this route was not covered in 2022 with the A330.

Great Airline
 

In an era of strikes and poor employee relations, how refreshing to see a news story like this.

From the outside, it looks a fantastically run business!

I’d be interested if any drivers, crew or airport/resort staff feel the same from the inside as what is shown from the outside….

I think that most of us at the coal face would definitely agree.

Brilliant. Long may it continue. Always a pleasure to fly with you on Jet2.

Please correct me if I'm wrong, but outside leases aside, haven't JET2 always prompted positive reviews from all quarters since their inception?

Anyone know what month the first new A321neo is due?

Very fluid situation but, at the moment, potentially April.

Thanks for the information
