The correct translation for "舱位紧张" in English is "tight cabin capacity".
When we say "tight cabin capacity", it means that there is limited availability of seats or space in the cabin. This can occur during peak travel seasons, holidays, or when flights are heavily booked. The term describes a situation where the number of passengers exceeds the number of available seats, making it challenging to secure a seat on a desired flight.
During such times, it is advisable to book flights in advance or consider alternative travel dates or airlines to increase your chances of getting a seat. Travel agents or websites often provide real-time information about cabin availability, helping travelers plan their trips accordingly. It is also essential to be more flexible with travel plans and have a backup option in case there are no seats available on the preferred flight.
