WestJet continues fleet expansion, adding Sunwing aircraft press release:
In total, 43 aircraft (including all former Swoop, Sunwing and Lynx aircraft) are scheduled for a full cabin reconfiguration before the end of 2025 to align with WestJet’s standard cabin layout.
That equates to almost 5 aircraft per month - I assume that some frames are already out of service getting reconfigured already, with less out of service over the summer?
