The aviation industry is calling for a ban on new flights operating through Suvarnabhumi airport to prevent further congestion.
The Airline Operators Committee (AOC), a coalition of 86 international airlines and 26 aviation service providers operating at Suvarnabhumi, is urging authorities to impose the ban immediately.
"Authorities should come to their senses and realise Suvarnabhumi can no longer accommodate more flights beyond the current level. We know it's a painful decision," AOC chairman Louis Moser told the Bangkok Post.
Overcrowding has become a critical problem at the airport, one that will become worse as the six-month "winter programme" begins in the final week of this month. Airport use is expected to rise by 10% during this period.
Suvarnabhumi has been operating beyond its design capacity of 45 million passengers annually for several years.
