Sorry Guys and Ladies,
but how many times do we need to make you all aware that it's not gonna happen at SOU with Jet2, as the 737-800 flying economically into or out of SOU is not possible with the runway there, and with the clearway/obstacle clearance issues which are a way different criteria to that of Southend SEN.
Jet2 do have 737-300's for now, that are suitable.
Hence as to why also no TUI nor Ryanair seen at SOU.
The A320 is what is suitable for SOU but Jet2 do not take their new A320N deliveries until 2028.
Jet2's spiritual home is BOH, but in IMO I cannot see them going there and taking on an even bigger TUI and Ryanair there, who are both now basing 2 x 737's for S24.
