Superjet International has declared Aeroflot should receive its first Superjet 100 this month, and begin revenue flights in June.
Tensions have intensified over the delivery schedule to Aeroflot, and the carrier has recently resumed attempts to impose financial penalties on Sukhoi for delays in delivery of its first aircraft.
Speaking at the RAA annual conference on 17 May, SuperJet International deputy senior vice-president of commercial Svetlana Issaeva said Aeroflot is due to take delivery of the first of 30 aircraft this month.
Aremenian carrier Armavia completed the first revenue flight of a Superjet 100 on 21 April. Since then Issaeva said the aircraft has completed 105 flight hours and 54 flight cycles. The aircraft has achieved 98% dispatch reliability in its first month of operations.
Issaeva stressed with more aircraft cycling into operation, it should be easier for the Superjet 100 "to speak for itself" with respect to the aircraft's spaciousness and level of comfort.
She also confirmed previous disclosures by Superjet that it would likely unveil plans regarding a stretched 100- to 130-seat version of the aircraft in June.
