Yes, you can book two flight tickets under the same name, but you must be extremely careful about the itinerary and timing. If you are booking two separate seats on the same flight (for example, if you are a larger passenger needing extra space or are transporting a delicate musical instrument), this is a common and supported practice. However, most airline Global Distribution Systems (GDS) use "duplicate booking" detection software. If you book two different flights for the same person that overlap in time (known as "impossible journeys"), the airline's automated system may flag one or both of them as a mistake and cancel them without notice. If you need to book for two different people who happen to share the exact same legal name (like a Junior and Senior), it is vital to ensure their dates of birth and middle names are clearly differentiated in the Secure Flight Passenger Data. In 2026, with the rise of biometric identity verification, airlines are becoming more sensitive to these duplicates, so always include unique contact information for each ticket to avoid having the system think you made a "double-booking" error.
