Alan ,
Are you certain it's the dreamliners that are cancelled ?
I'm not booked on a dreamliner , but have never received confirmation of my flights ?
Yes - I spoke to them this morning. Three Ethiopean Airline Dreamliner flights. Kiev have given slots to 60+ private jets (probably very lucrative) and they pushed back on WCS saying the Dreamliners are too big.
Give them a call or email about your e-ticket. Have you had the text confirmation?
They included the fan information pdf in the email with the e-ticket and it bounced back from my usual email address because it was too big. They sent it to a different email and it went through ok.
