This report from @sphasiaone says that EVA Air is bringing back its Hello Kitty jets, which last flew between Tokyo and Taipei in 2009.
It was such a hit back then and the company is hoping that it will revive the route that was battered since the March 11 earthquake and tsunami.
The airline said there will be changes to the look but to get an idea on how a Hello Kitty jet and its in-flight services look like, here are some pictures from the net from the previous campaigns.
