Dogs must lie on an absorbent mat either in front of your seat or the adjacent seat if space is available.
Where?
How much space is left in front of your seat?
No spare adjacent seat perhaps?
Perhaps there is more to this than meets the eye! How much space was available on the flight? Maybe it had nothing to do with her not supplying her own absorbent mat...
Wonder if there will be any legal action?
Cheers, HH.
PS: How about a bit of lateral thinking, she had a beach towel, surely if this was laid over a bin liner (freely available from catering) this would have been acceptable. Is there an Australian standard for absorbent mats?
