Unfortunately, Nepal Ordinary Passports do not have Thai Visa Exemption and cannot get Thai VoA (Visa on Arrival)....

Do note that airport transit more than >12 hours, should obtain a Thai Transit Visa "TS" >

No problems about visas since a Thai visa is not necessary for transit within Suvarnabhumi Airport....

But, 80 minutes for transit and luggage transfer between 2 international flights at Suvarnabhumi Airport = you (transit passenger) may board the connecting flight in time, but there is a risk that your transfer luggage may not get transferred on the airplane in time....considering early evening (5pm-6pm) arrival and departure is a busy time....

Also, a note for those with dual/multiple passports, you cannot swap passports at land borders: do it with an airport entry/exit or airport transit....

At land borders, border/immigration officers are going to ask for entry/exit between the two bordering countries in the same passport....

As tomorrow is a Thursday, no issues at all about any possible super busy crossing from Vientiane into Nong Khai such as the situation like on Friday afternoons and the weekends. A late afternoon, or even sunset crossing should be fine. But enjoying something to eat/drink in Nong Khai before boarding your train is good too!
