Are there any potential issues I might face traveling from the UK to Bangkok for 30 days with a connecting flight to the USA?

The travel plans from the UK to Bangkok (BKK) for 30 days with an onward flight to the USA appear straightforward. However, it's important to note that the 30 days include both the arrival day and departure day, effectively limiting the stay to 29 nights. Additionally, having the outbound ticket to the USA purchased prior to departure from the UK is advisable to avoid any airline or immigration issues. Potential concerns include dealing with Bangkok's traffic and ensuring adequate funds for the trip.
