Locationship refers to a brief romantic encounter usually occuring while traveling or on vacation, occasionally outwardly resembling a conventional relationship, but without any underlying comittment. May be rekindled at future opportunities. 

旅途恋情指的是发生在旅程或者度假期间的短暂的浪漫邂逅，表面上或者像是传统恋情，但没有更深的承诺。也许两人的恋情会在日后复燃。

The word locationship is often used with slightly negative overtones, carrying the implication that a relationship is not long-lasting and meaningful, but based purely on convenience and physical proximity. 

旅途恋情这一说法使用时略带负面含义，暗指这并非长久恋情，也并无太大意义，而纯粹是基于交往的便利以及两人的接近。
