Thanks OltonPete.
I came in on the 733 from NCE on the 18th, partly the reason for my question.
Delays were about 1 hr in each direction which at this time of year I don't think is too bad. I don't have complaints about the operation of the flight, but have to say that I think it is short sighted to be leasing in LY-SKA. Very tatty aircraft and not what I paid for when I booked, although as mentioned earlier on this thread it won't be cheap for Mon, it must be cheaper than leasing something comparable with the Mon aircraft based at BHX.
It was not apparent at booking or at any time prior to boarding that it would be operated by aleased aircraft.
Looking at the registrations the average age of the Mon BHX fleet is about 11 years. I like Monarch, which is why I booked with them this time, and have booked my mum on a flight with them this week to Rome, but this was a let down.
