Add to the above with Eastern covering for KLM, other airlines suffering PW GTF engine woes on A321N fleets are JetBlue and Air Transat who both will see themselves this summer way short of aircraft that will be out of service for engine inspections that may take up to 2 months per aircraft to fix.
For Air Transat who have gunned everything on going A321Neo LR over the 'Pond' with a new fleet of 15, this will have huge financial impact on them, which could see up to 9 airframes 'parked' for the engine repairs.
The groundings are due to mandated inspections of PW1100G engines manufactured by Pratt & Whitney. The engine inspections are likely to see aircraft out of action for two months at a time, disrupting the busy Transatlantic high season summer flight operation, and it is noted that the problem affects all Carriers operating the type with the same engine.
Air Transat A330's are redeploying onto routes usually operated by the out-of-service A321Neo and has secured the lease of three additional A330-200s to support its network needs and will offset A321-200NX(LR) groundings.
Canada's Air Transat is also due to add the A321NX (XLR) with 4 new aircraft from next year.
