Not only the mood but the company rules If a traveler is denied entry by immigration upon arrival, the airline is legally and financially responsible for flying them back to their origin point. That is why now most request an outbound or return ticket. Many countries fine airlines heavily if they bring in a passenger who lacks proper entry or exit documents and because your original time you can stay (without extension) do not match the returndate they play it safe and ask for an outbound ticket. If you can convince the carrier clerk or his chef that you are a regural tourist who will not fail immigration rules maybe you can check in. 1 class passengers mostly get more chance I would not risk it buy a refundable ticket or a cheap trow away outbound ticket if your plan to extent your visa/visa exempt.
