专家警告说,数字登机牌如果不适当展示,可能会造成飞行延误。 Digital boarding passes may cause flight delays if not properly displayed, experts warn.

数字登机牌问题很普遍,可能导致旅行者误机,因为有些乘客由于手机上没有适当展示或无法进入通行证而被拒绝登机。 A widespread issue with digital boarding passes may cause travelers to miss their flights, as some passengers have been denied boarding due to passes not being properly displayed or accessible on their phones. 专家警告说,如果登机证没有满载且无法在电话的传票簿或航空公司应用程序中看到,而条形码或QR码无法扫描,即使有效票也会引起问题。 Experts warn that even valid tickets can lead to problems if the boarding pass isn’t fully loaded and visible in the phone’s passbook or airline app, with the barcode or QR code not scannable. 在繁忙旅行期间严格执行登船规则时,风险更大。 The risk is higher during busy travel periods when boarding rules are strictly enforced. 建议旅行者提前检查他们的通行证,确保能看得见和扫描,并考虑通过航空公司的官方应用程序或网站携带打印备份或核查身份。 Travelers are advised to check their pass well in advance, ensure it’s viewable and scannable, and consider carrying a printed backup or verifying status via the airline’s official app or website.
