Went to see Olga's agent this morning who has been holding her flights. Well, 8 return trips for 4 people. No wonder no flights were 'available' when this is what they do.
Singapore had nothing available, so she quoted us to fly into Athens and out of London $2399 with Thai. Nothing cheaper on Etihad or Emirates.
Got home, went straight on the internet and found flights with Singapore for slightly cheaper, but the EXACT SAME flights with Thai for $2153 each. Plus a $18 booking fee. Sheesh. Wonder how I'll book?
