Grupo Mexicana suspended operations at its three airlines Saturday "until further notice," citing the financial problems inherited when the group changed owners a week ago.

The company's three airlines - Mexicana Airlines, MexicanaClick and MexicanaLink - stopped all flights at midday Saturday, according to a statement from the group.

The company advised passengers still holding tickets to consult its website to apply for refunds, or for those traveling Saturday, to contact Grupo Mexicana for assistance.
