Perhaps it will do thinner and leisure routes into SE Asia etc where it’s a bit of a stretch for a 737 and little/no competition, eg Chiang Mai (ex QR), Krabi (former destination via Yangon), Langkawi, Penang, Siem Reap, Phu Quoc, Vientiane.
Can’t see them being sent to Europe, would have thought a 737 is sufficient for anywhere they could or already fly to.
