Automated Onward-Travel Proof App

Job ID: 40148371

Budget: $30 – $250 USD

I am building a niche travel utility website that allows users to book temporary flight reservations for visa applications (often called 'Onward Tickets'). I need a full-stack developer to build the Minimum Viable Product (MVP).

Core Requirement: The system needs to generate a valid 6-digit PNR code that stays active for 24-48 hours and can be extended for long perious even 14 days if possible.
Constraint: I am a tech-savvy solopreneur, not a travel agency. I do not have IATA accreditation.
Solution: You must integrate a non-IATA aggregator (like Duffel/Kiwi) OR write a script that automates the 'hold' function on airline websites.

Scope of Work:
Backend: Develop the engine that secures the PNR without manual intervention.
Frontend: A high-converting, single-page application (SPA). Input details -> Pay -> Auto-download PDF.
Delivery: The user must receive the PDF immediately after payment.

To Apply: Please explain your technical approach for generating the PNR without an IATA license. Proposals that do not address this specific constraint will be archived.
