Suvarnabhumi airport has added more hotel counters for inbound passengers after reports of chaos in the passenger arrival area.

The airport general manager said nine more counters for hotels had been added on the second floor, reserved for inbound air travellers, taking the total to 17.

The move followed complaints by airport users on social media on the weekend. Pictures showed frustrated passengers looking for the names of the hotels where they wanted to stay or had made reservations before travelling.

"Hotel staff shouted the names of their hotels and desperately shook their heads. When passengers complained to them, hotel staff told them to complain to Airports of Thailand," a post on the Twitter account @spin9 said.

Airports of Thailand manages Suvarnabhumi and other international airports in the country except Samui.

Arrivals at Suvarnabhumi have risen since the lifting of pre-travel RT-PCR testing on April 1.

AoT predicts even more passengers passing through Suvarnabhumi and other airports during Songkran.
