对于商用航空业来说，2020年上半年将是一个糟糕的时期。但是自6月以来，机队的活跃数量逐渐增加，给航空业带来了一线希望。

The first half of 2020 will go down as a terrible time for the commercial aviation industry. Since June, the active aircraft fleet has been increasing gradually, providing a glimmer of hope for the industry. 

去年飞行时数创纪录的下降可能促使飞机退役激增，但实际情况恰恰相反。除了2020年3月飞机退役高峰的137架飞机以外，由于运营商推迟了机队的重组，因此2020年其他时期退休飞机数量更低。

While the record-setting decline in flying last year could have prompted a spike in aircraft retirements, the opposite occurred. Aside from a peak of 137 retirements in March 2020, monthly retirements were generally lower in 2020 as operators deferred fleet recapitalization. 

所有这些情况，以及航空公司已经以更多的航班量安排到2021年4月的时刻表，这表明市场已有所改善，但尚未出现全面的复苏。

All these, along with airlines scheduling flights through this April at much higher rates, shows improvement in the market but a fully-fledged recovery has yet to occur.
