Had a OW flight into DEL, and booked a separate Vistara ticket to SIN.

Unfortunately, Vistara staff at the International Transfer area in no uncertain terms stated that they could not check me in there, and I had to go through immigration into India.

Is this standard policy for Vistara? lf so, a good point to note in this thread; if not, perhaps Vistara should know to adjust their training…
