Bombay was a restart, it had been suspended for a few months.
It was suspended in May 2009 right after a period of deregulation meant BMI, Virgin, Kingfisher and Jet Airways all bailed in at the same time, then realised nobody was making much money. The impetus to go back was Kingfisher going bust in the end, bmi having walked away a while back.
MAN-LAS had been a year round B744 which they tried on an A330 last winter. It seems with MAN going to be an all B744 operation, winter ops to LAS aren't profitable enough with the capacity being used on winter sun out of LGW.
