The correct response related to "舱位很紧张" in English would be "The cabin space is very limited."
When we say that the cabin space is "very limited," it means that there is a shortage or scarcity of available seats or room for passengers in the aircraft. This situation often occurs when the flight is fully booked or during peak travel seasons. As a result, there might not be enough space for passengers to stretch their legs, store their belongings or move around comfortably during the flight. It is advisable to book tickets in advance or consider alternative travel dates to avoid the inconvenience caused by limited cabin space. Airlines are continually working to optimize space utilization and improve passenger comfort, but during periods of high demand, it is essential to be aware and prepared for the tight cabin conditions.
