What to do if…
you are told you need an electronic travel authorisation and you do not have it in time

Short answer

Confirm the requirement on the official government site (for example, ESTA for Visa Waiver Program travel), then choose one path fast: apply correctly right now or rebook. For Visa Waiver travel to the U.S., you generally need ESTA approval before boarding.

Do not do these things

  • Do not use a “visa/ESTA helper” site that charges extra or collects unnecessary personal data.
  • Do not assume an airline can “override” a missing authorization at the gate.
  • Do not submit multiple new applications with different answers in a panic (it can create delays and confusion).
  • Do not ignore passport mismatches (wrong passport number, expired passport, different nationality) — they are a common cause of failure.
  • Do not buy a new non-refundable ticket until you’ve asked about changing the current one.

What to do now

  1. Get clarity on what you’re missing. Ask the airline/agent: “Which authorization is required for this itinerary and this passport?” Screenshot the message if it appears in the check-in app/website.
  2. Verify the rule on official government information for the destination (and any transit points). For U.S. Visa Waiver Program travel, confirm:
    • you’re eligible for the VWP,
    • your passport meets requirements (often an electronic “e-Passport”),
    • your trip purpose and length fit the VWP.
  3. If it’s U.S. ESTA and you’re eligible, apply on the official ESTA site immediately. Save your application number. USA.gov says it may take up to 72 hours to find out if you’re authorised under the VWP—so if you’re inside that window, plan as if you may need to rebook.
  4. Make the “rebook vs wait” decision using one deadline: the airline’s check-in close time. Tell the airline: “I have applied for ESTA and will update you—what is the cheapest way to move this booking if approval doesn’t arrive before check-in closes?”
  5. If you’re not eligible for ESTA/VWP (or you need to stay longer/work): switch to the visa plan and rebook. Use official visitor visa information to understand the correct category and what you’d need to do next (application, interview, timing).
  6. If you must rebook, reduce the chance of repeating the problem. Before paying:
    • re-check authorization requirements for every country on the itinerary (including transit),
    • confirm the authorization will be tied to the same passport you will present.
  7. Start the “coverage” track (quick checks).
    • Review your travel insurance and credit-card travel benefits for exclusions related to “failure to obtain required travel documents/authorizations.”
    • Save proof: screenshots of the requirement message, application receipt, and any status page.

What can wait

  • You do not need to argue at the gate—focus first on getting a workable later departure.
  • You do not need to figure out the root cause immediately; prioritize correct passport details and official application/status steps.
  • You do not need to file complaints now; you can do that after you’ve stabilised travel and lodging.

Important reassurance

Getting caught out by an electronic authorization is very common, especially when rules change or you renew a passport. The fastest path is usually one clean official application and a clear rebooking decision if the timing won’t work.

Scope note

These are immediate first steps to prevent scams, avoid duplicate applications, and buy time with airlines. For complex eligibility issues or urgent travel, you may need professional immigration/legal advice.

Airlines can deny boarding when required documentation/authorization is missing. Always use official government channels for applications and status checks.
