Thank you for responses from all. The situation is quite confusing. As noted, there are some flights operating, such as Vande Bharat Mission flights on Indian airlines which are operating for Indian nationals. I also see some flight schedules listed on Thai Airways website, but I do not know if they are operating. On one of the local facebook sites, it seems to indicate that they are. If so, wondering if one of these options could be used as a connecting transit option to Eva Air, or China Airlines. In addition to trying to get best connection time and stay airside, another problem seems to be whether or not you can check bags through from Delhi all the way to Taipei.
