我們之前說過，紅眼航班（red-eye flight）是深夜出發、第二天凌晨抵達的航班。其實，夜間出發或到達的航班還有粉眼和紫眼之說。

Pink-eye flight is a relatively short flight that leaves late in the evening. A purple-eye flight is a flight that is taken or arrives at midnight.
粉眼航班指夜間出發、航程相對較短的航班。紫眼航班則指午夜出發或到達的航班。

For example:

My flight to Sibu was delayed from 8:25 pm to 10:00 pm and then to 10:20 pm, just missing being a red eye flight by 1 hour and 41 minutes. I guess that makes it a pink eye flight.
我去詩巫的航班從晚上8:25延誤到晚上10點，之后又延誤到10:20，再差1小時41分鐘就成紅眼航班了。我估計我這個航班應該算粉眼航班了。
