does not have any widebodied aircraft configured/sold in an all "Y" seating configuration. So the answer to your question is yes, and no.
On certain routes, the forward J/C cabin is sold as "S" class or SuperComfort. This is usually allocated to customers who have purchased full Y/C tickets are high end excursion fares in Y/Q/B/M classes. The level of In-Flight service is identical throughout the aircraft. Such routes include MAN

Vacaction flights, the "BIG SEATS" can be purchased for a surcharge.
On other routes the entire aircraft is sold in an all Y/C configuration, and the forward cabin is available on a first come first serve basis. Such an example would be AC
