Irregularities marked the first day of advance bus ticket sale that started in the city on Tuesday ahead of Eid-ul-Azha festival, ticket aspirants claimed.
They also alleged that officials of different bus companies sold tickets for some specific days on the black market, but the operators denied the allegations brought against them.
Eid-ul-Azha is likely to be celebrated on August 22.
Hundreds of people thronged the bus counters since the early morning to buy advance tickets to go home on the occasion of Eid.
There was more demand for the tickets on August 19 and August 20.
Many ticket aspirants returned home empty-handed as the operators said the tickets for August 19 to August 20 had already been sold out.
A section of ticket aspirants told the FE correspondent that the tickets for August 19 and 20 had been sold out by 11:30 am on Tuesday.
Iqbal Hossain, an assistant merchandiser of a buying house, told the FE outside the SR Paribahan counter at Kalyanpur that he had been waiting in a queue for the tickets since 5:30 am.
"My serial was just 25. The ticket seller told me at 10:30 am that all allotted tickets for Dinajpur had been sold out," he said.
He claimed that most of the tickets were stocked by the operators which might go to the hand of black marketers.
However, advance ticket sale was rescheduled to August 07 from August 05 by the operators amid the ongoing student protest over road safety.
Eid-goers also claimed that they couldn't get tickets even online.
Md Badrul Hayder, an NGO official, told the FE that he tried for hours to buy tickets on August 20 of Nabil Paribahan online, but failed.
Mohammad Shafiq, manager of Nabil Paribahan, told the FE that most of the people were demanding for tickets on August 19 and August 20.
He said his company will provide 120 buses daily for ten northern districts ahead of the festival, the capacity of which will be maximum 4,500 a day.
"But the demand is five times than the capacity," he said.
Bangladesh Railway will start selling advance train tickets from this morning (Wednesday).
Advance tickets for August 17, 18, 19, 20 and 21 will be sold between August 08 and August 12 respectively.
