Agreed. Rumours like these are terribly damaging - and boy, do they travel fast. I remember some years ago, the Company I was working for had to pay cash for fuel for about 4 days at a major European Airport -because someone at head office messed up the payment schedule/details. Instantly, I was getting 'phone calls asking how secure I was and how long we were going to last. I was still working for them 15 years later.
MYT people must be damn frustrated with these rumours - I even heard someone on Radio 4 questioning a 'travel expert' on what compensation was in place if MYT went out of business. I hate this sort of thing because it's based solely on rumour, but directly affects the listening public's booking plans, and can risk fulfilling the prophecy all by itself.
