As reported here a couple of days ago, the HOP! brand has been axed, but not entirely.
Air France is to rebrand it as AirFrance HOP (dropping the exclamation mark and diminishing HOP ago a sub case below AirFrance). The rebrand will begin immediately, and the tail livery will be replaced as AirFrance standard.
The airline was amalgamated in 2013 from BritAir, Air France Régional and InterAir, into HOP! However new CEO Ben Smith didn’t see the point of its lack of relationship with the main airline brand.
