The allusions not correct or ordered of course...
BAW commenced JFK ops ex LCY in 2009.
Odyssey was not even mooted until 2016.
Odyssey were never a serious player...a crowd funding paper airline project taking advantage of the publicity at the time abetted by the manufacturer of a new airliner on the block..
The "turf" BAW was actually protecting was their very high end market ex LHR & a "project" within BA thought it a good idea to attempt to nail down that traffic by flying ex LCY & encouraged by LCY...Prestige for both simple as..."Speedbird One" still no coincidence.
The project obviously overrode the alleged bean counters with the counter argument that although not totally quantifiable but effectively still a non profit operation it would deny competitors ex LHR very important revenue & clients & close a win that way ultimately.
Killing the competition was a BAW thing back in those days still.
Covid was the end or handed excuse finally as the operation was already being wound down long before.
The fact that no other destination was flown is indicative in it`s own right.
When has BAW ever stuck with anything spun out of & away from the "fortress" anyway.
The A318 was never the right aeroplane operationally with it`s lack of performance westbound from a severely limiting r/w but pre-clearance & fuelling at SNN helped mask those difficulties & was actually cleverly marketed as advantageous to the client.
The A318 was a misfit in the BAW fleet...itself a cobble up by Airbus to "fit" a perceived market back in the day (probably a home market spec briefly proposed by Air France.)
