第五自由航班允许航空公司通过本国在外国城市之间搭乘旅客,在使用不足的路线上削减费用和票价。 Fifth freedom flights let airlines route passengers between foreign cities via their home country, cutting costs and fares on underused routes.

根据一项81年之久的航空协定,第五自由航班允许航空公司在两个外国之间载客,如果旅行在本国开始或结束,可提供较低的票价和更好的奖励座位供应。 Fifth freedom flights, allowed under an 81-year-old aviation agreement, let airlines carry passengers between two foreign countries if the trip starts or ends in their home country, offering lower fares and better reward seat availability. 阿联酋、万塔、新加坡航空公司和埃塞俄比亚航空公司等航空公司使用这些路线——如悉尼至赫里斯特彻奇或法兰克福至纽约——填补空席位,降低费用,扩大服务范围,而不增加飞机。 Airlines like Emirates, Qantas, Singapore Airlines, and Ethiopian Airlines use these routes—such as Sydney to Christchurch or Frankfurt to New York—to fill empty seats, reduce costs, and expand reach without adding planes. 这些航班很少,需要双边批准,限制使用这些航班,但为在使用不足的路线上旅行的人提供大量节省和优惠舱位。 These flights are rare and require bilateral approval, limiting their use, but provide significant savings and premium cabin access for travelers on underused routes.
