I will fly to Singapore the day after tomorrow, why should I arrive at the airport 2.5 hours in advance. Are there any precautions? Please be specific.

You need to go to the airport in advance to take international flights, earlier than domestic flights. This is normal, because you need to leave enough time to clear customs. When going to Singapore, you should be careful not to bring too many cigarettes with you. You will have to declare them when entering Singapore, and they may be confiscated or have customs duties levied. Nothing else, if you have any questions you can ask me.

Have a pleasant trip to Singapore!
