I want to go from HKG to DEL and MUM back to HKG.
If I fly this exact route, its almost 2,000USD. However, If I base out of Taipei (TPE--HKG--DEL, MUM--HKG--TPE), the flight is only 700USD. Is it possible to buy the flight out of Taipei but not actually be on that leg of the flight and just check in at the check in counter in HKG for the HKG leg? Will they give me any issues at the check in desk?
