Britt Ekland and her pet pooch were removed from business class on a flight from LA to Stockholm.
It emerged that an administration mix-up saw the pair's seats double booked.

The former Bond Girl, 74, had booked two seats for her and her dog, called David Bowie, but KLM were unable to find a record of the booking, despite the fact the actress had received a confirmation email.
When another passenger came along to sit in the seat, Britt was asked to leave.
The scene was described as "embarrassing" for Britt as she was removed and put on an Air France plane a few hours later.
Speaking to the Daily Mail, a source said: "In the end, KLM admitted it was their error and paid for Britt and David Bowie to fly with another carrier an hour later."
Britt took to Instagram to share her experience. She posted a pic of Bowie and wrote: "The flight that never was! Bumped off @klm and put on @airfrance instead!!!! Not nice behaviour of @klm."
She also shared a picture to say that they were finally on their way.
However, Britt also shared an image showing how loyal she has been to KLM, displaying a number of gifts she received for flying business class between LAX and Stockholm with them nine times. She suggested she did not feel that they were as loyal to her.
In case you thought I used @Klm casually this shelf of business class "gifts" which I really loved, shows that I made 9 business Rt flights lax/Sthlm, so I don't feel that @Klm after having been booted out of 3A on yesterday's flight are loyal to their passengers and this will be thrown away, sad as they are so pretty but out they go, no mercy!
