Using the “Same as Previous Traveler” Shortcut
During our test submission for a family of 6 in January 2026, we found that using the “Same as Previous Traveler” shortcut saved 3 minutes per person, but we had to manually re-enter hotel details for members arriving on separate flights.
| Scenario | Action |
|---|---|
| Shared flight and hotel | Select “Same as Previous Traveler” |
| Different flights or hotels | Enter data manually |
Group Members with Different Flights or Accommodation
The tdac group submission permits independent itineraries within one batch. Skip the shortcut to manually enter different travel details.
TDAC for Groups Larger Than 10 Travellers
For a tdac group of 10 or more, split into batches of up to 10. Each batch needs a separate submission using the “Add Other Travelers” feature.
Practical Tips for Family and Group TDAC Submissions
Draft saving is unavailable. Prepare passports beforehand, use a parent’s contact for children, store individual QR codes in a shared folder. Read the TDAC user guide for technical requirements.
- Contact Details for Minors: The TDAC system allows parents to input their own phone number and email address for children.
- Passport MRZ Scanning: The system requires manual processing; scan each passport’s Machine Readable Zone (MRZ) one by one.
- Editing Locked Fields: If a traveller makes an error in a locked field (name or passport number), they require a new submission. Modifying one person’s record does not invalidate the rest of the tdac batch submission.
