Sorry Pin, I missed one of your questions. New aircraft is the fleet rollover to the Max and additional 787-9s. In terms of airframe numbers it's +1 and a bit due to them moving around the Group. Pilot numbers will be up IMHO as the 787 starts to really spread its wings and start long runs with a resultant need for more pilots per airframe, longer rotations, 3 crew ops etc.
SH is less certain but history has shown that TUI is big enough yet agile enough to shift emphasis pretty quickly if needed. Spain was hurting badly with the rise of Turkey and Egypt, IMHO we'll see a bit of a rebalancing what with very recent events.
The Nordic LH operation is also blending nicely with new routes opening there with us operating Vietnam sectors from March as well as the current KBV and HKT etc. We're also doing a fair bit of their Caribbean. Some of their pilots have been integrated into our operation for this reason. Flexibility here is also paying dividends after the political pissing contest between Russia and Sweden, the 787 has the legs to go the long way round avoiding Russian airspace, the 767 doesn't so 78s have been switched out to Nordic and 76s to the Caribbean.
Canada is still a viable operation again cooperation and flexibility paying off as we have UK and Belgian airframes and crews out there which justifies extra airframes in the UK in summer. Important point here is that the pilots are a secondary consideration in terms of airframe numbers; if you can get work for the airframes year round you get the pilots. Have a squint round MAN at the number of UK airframes parked up. Now look at the paint jobs; not much blue.
Enough. I'm even boring myself!
