I'm signed up with the ME 3 for emails of their special offers. Generally there will be a sale on 3 or 4 times a year and if you can book about 3 months in advance there are some good deals available.
SCOOT have seats with additional legroom available, a sale fare on their business class could be a good deal compared to a normal full service airline fare. Some previously non profitable routes to secondary European cities could be opening up next year. Whilst Emirates have good European coverage their fares can be on the high side where they have little competition.
Turkish Airlines operate narrow bodies to secondary cities in Europe not covered by the ME 3 and given recent events may have some cheap fares on offer.
I try to avoid the B787 in 9 across and the B777 in 10 across configurations.
