Planned into SZB, heard it's going to LOT Poland, not confirmed though.

Des anyone know why it isn’t flying above 28000? All three sectors that’s been max altitude?

Probably an air pack is US

A single pack op would limit them to FL250. More likely to be an RVSM critical item or authorisation issue.

Or just avoiding the jetstream

UIK continued to MCT from SZB yesterday, (also with a max altitude of 28,000)
This would make sense if the reports that it's going to LOT are correct, routing to Europe.

UIK arrived in Toulouse overnight.

I expect it may be heading for a paint-shop before starting a new life.

UKH departed MCY at 0800 for PHE and onwards later today to SZB (Kuala Lumpur Subang).

UKH, like UIK is cruising at a lower altitude - 26,000.

UIK was deleted from VH-reg on 15/05/24 as exported to Exported to - Isle Of Man
