**The family member’s ID-card plan may help establish Bosnian citizenship, but it does not by itself establish permission to board.** I could not verify a published procedure under which Sarajevo officials accept an ID delivered by a relative and issue clearance to the airline.

Two rules matter here:

- **The Croatian passport falls short of the ordinary entry requirement for foreign visitors.** Croatia’s Foreign Ministry confirms that passports or identity cards must remain valid for at least three months after the planned departure from Bosnia. Forty-nine days is insufficient. [Croatian Foreign Ministry](https://mvep.gov.hr/services-consular-portal/consular-information-22802/visas-22807/visa-requirements-overview-22879/22879?country=17)
- **Bosnian citizenship changes the immigration position, but documentation still matters.** Bosnia’s Border Police says that a Bosnian citizen with another nationality is not considered a foreigner in Bosnia. It also expressly says that a Bosnian ID card cannot serve as a valid travel document for journeys to or from EU or Schengen countries. Consequently, even having that ID in Lisbon would not fully resolve this itinerary. [Border Police FAQ](https://granpol.gov.ba/sr/najcesce-postavljena-pitanja)

If the passenger reaches Sarajevo, the original ID could help officials verify identity and Bosnian citizenship. Whether they will accept the proposed arrangement needs a direct decision from the airport’s Border Police. **Do not assume that a family member waiting with the card guarantees admission or boarding.**

With departure only hours away, the practical steps are:

1. **Have the family member call Sarajevo Airport Border Police immediately:** **+387 33 755 359**, email **sarajevo@granpol.gov.ba**. Explain both nationalities, the Croatian passport’s expiry date, the unavailable Bosnian passport and the original ID in Sarajevo. Ask whether they will admit the traveler on those facts and whether they can communicate that decision directly to the airline. These are the unit’s [published contact details](https://granpol.gov.ba/hr/postrojbe-granicne-policije6).
2. **Speak to Lufthansa’s airport check-in supervisor in Lisbon immediately.** Request coordination with Sarajevo Border Police and the airline operating the Sarajevo leg. Provide photographs of both sides of the Bosnian ID as supporting evidence. Ask what official confirmation they require and whether it covers boarding at the connection.
3. **Obtain explicit airline acceptance before relying on this arrangement.** Lufthansa’s conditions require presentation of the necessary documents before travel and allow refusal when documents are incomplete. Border Police confirmation would therefore need to satisfy the airline’s document-check process. [Lufthansa conditions, Article 13](https://www.lufthansa.com/fi/en/terms-and-conditions-lh)

If this coordination fails, ask a Bosnian consular mission about a **putni list**, an emergency document for return to Bosnia. Issuance and acceptance on the connecting itinerary would need checking; obtaining it within a few hours cannot be assumed. [Bosnian embassy guidance](https://varsava.mvp.gov.ba/bs/putni-list)
