A very good point PETER01 - EF does indeed show today's BA2159 to UVF as a 4-class
FR24 - which I appreciate is not necessarily reliable! - has G-YMMR down as operating LGW-LAS today. Perhaps one of the BA insiders could confirm what airframe is currently assigned to BA2159?
It looks like a 14F/48W on the UVF route, which should be Thales IFE or refurbed/densified with the new Panasonic IFE.
