续程机票合法吗？
Direct answer
是的——使用离境机票是合法的。带有真实PNR的已核实航班预订是满足航空公司办理登机手续和签证申请要求的合法文件。提交您最终未实际乘坐的真实预订不构成欺诈；预订在航空公司系统中与提交时完全一致。
Statutory distinction: genuine GDS reservation vs. forged PDF
Immigration and consular regulations require documentary proof of planned onward or return travel; they do not make it a criminal or civil offense to later change your travel plans or let an unpaid hold expire. Under EU Visa Code (Regulation (EC) No 810/2009, Annex II), applicants are explicitly asked for a "return or round-trip ticket, 或其预订"." Under U.S. Visa Waiver Program regulations (8 CFR Part 217) and the Schengen Borders Code (Regulation (EU) 2016/399, Article 6), travellers must demonstrate onward travel plans within their permitted stay.
When a document crosses the legal line
Two practices are unlawful misrepresentation: (1) editing or doctoring a PDF to display a false PNR, date, or passenger name that does not match the airline system, and (2) using a template generator with no real GDS booking behind it. OnwardTicket.us creates a genuine, temporary reservation in the airline GDS—never a fabricated PDF.
Important limitations
A flight reservation is a temporary unpaid/held itinerary (valid 48 hours standard or 7 days with the paid add-on), not a purchased e-ticket for boarding. Furthermore, PNR verification confirms only that the booking record exists in the airline/GDS system while active; it does not guarantee boarding or immigration admission, which remain subject to carrier and border-officer discretion.
