Virgin Australia has opted for a two-class configuration for its fleet of Embraer E190-E2s, the first of which
will be entering into service in October this year.
Revealing its cabin interiors for the first time, the Australian carrier adds that it expects to take delivery of four – out of an order for eight – E2s over a 12-month period.
Embraer will begin assembly of
Virgin Australia’s first E2, christened ‘Coral Bay’, in March, the airline confirms. The E2s, which will operate with regional unit Virgin Australia Regional Airlines (VARA), replace the carrier’s fleet of Fokker 100s.
