Air Exel (Maastricht) and its sister companies AlsaceExel (XT/Strasbourg) and LoirExel (XT/St. Etienne) have suspended their ATR 42 operations earlier this week due to financial difficulties of parent Exel Aviation Group. HollandExel (HXL/Amsterdam) and BelgiumExel (Brussels) are still operating charter flights using their joint fleet of B767-300ERs.
