Yeah, G-JZHA (formerly D-AHFY from TUI [aged 13.9 years old]) has arrived at EMA today from Hannover as EXS51D. I expect that the aircraft has flown into EMA to undergo the treatment of Airbourne Colours (based BOH and more recently EMA) to receive its new paint job.
D-AHFS and D-AHFR (to become G-JZHB and G-JZHC respectively) are to be leased from AerCap, but aged at 14.7 and 14.8 years respectively, I'd expect we'd see them for a long time yet! Still, great to see such a good UK airline expanding like Jet2!
