What are the best options for extending my stay in Thailand if I've already entered on a 30-day visa?

@Allan ***********

some airlines don't want to take the risk that someone may get turned away from the border for not having an onward flight within the 30 day visa exempt period (or that of one's visa if short term). This can happen at the airline's expense which is why they can be rather strict about onward flight requirements for someone about to embark on a long distance flight.

Just google Thai visa application and scroll down you'll find it

The E/Visa can be nerve racking,applied 5-6 weeks ahead of departure and after numerous emails/phone calls (being told it’s in process do not call again/No response to emails.1 final call 3 days prior to departure,an Embassy employee was polite enough to say let me check for you,she came back on the phone and said it had been approved 3 weeks ago and was sitting in the email system and the person responsible had neglected to issue it.She said I’ve sent him an email of urgency and I finally received my Visa 48 hrs prior to departure.That is totally inexcusable.I have applied again for my next trip and hopefully the system will live up to its claim of ( 10 to 15 days MAXIMUM)On my flight last year,some travellers had NOT received their E-Visa at all after weeks.Not good enough.Things must improve.JMO.Any other tourist experience d the same frustration?
