I've flown x2 with Turkish airlines, return journies so x4 flights.
Just had box damaged once on flight out. Forks needed tweekin before I started my around Sri Lanka trip.
Bike boxed on all occasions.
I think damage occurred when corner dragged along tarmac.
Not put off. So same airline for my Ethiopian tour in Feb.
From UK, Edinburgh to Addis Ababa via Istanbul.
Fingers crossed.
