PH-KCB should be taken off the list above. It seems to still have the old seats. The status of PH-KCK is unclear. Meanwhile, PH-KCI, PH-KCE and PH-KCF have been in the hangar for about ten days each, so they could all have the new seats installed:

New seats:

PH-KCA
PH-KCC
PH-KCE
PH-KCF
PH-KCG
PH-KCI


Old seats:

PH-KCB
PH-KCD (currently under maintenance)
PH-KCH
PH-KCK (?)
