Not sure on the LBA B757 operator - doesn’t look like Titan as they aren’t configure to this.
Looks like BHX will be getting a Smart Lynx A321 y220 seats for summer.
STN is getting 2 A321’s with Y212 config. GPOWN confirmed and another A321 from Titan (sources but to be delivered to them yet)
GVYGL and GVYGM A332’s will be MAN based.
Awaiting confirmation of EC-IDT returning next year to PMI.
