I applied for a 60 day visa and at first the embassy requested a return ticket to Canada which I submitted. Now they are asking for a airline ticket leaving Indonesia but the problem is I don't quite know yet where we will be leaving from to purchase the ticket. We will be heading to Flores from Ubud or maybe Pemuteran. After Flores we are heading to Luang Prabang Laos. Any help you can offer to help me sort out the flights so that I can respond to the Embassy would be greatly appreciated.

Show them all your tickets, where ever you are going from Indonesia and back to Canada = problem solved!

I don't think you'll be able to get around this requirement. All travelers who arrive in Indonesia without stay visas, must hold outbound tickets, either air or sea. A flight within Indonesia won't do it. It has to be from Indonesia to another country.

On occasion, travelers who secure visas on arrival in Indonesia may be asked to show proof of their outbound tickets. Enforcement is inconsistent, and they seldom ask but it does happen.

They may accept a ticket from (for example) Hong Kong to Canada, or they may not. They are very literal.

It's like their passport 6 month validity policy. It's illogical, but unarguable.

Perhaps you could ask your travel agent to issue a ticket from Jakarta to Hong Kong (again for example) that could later be refunded or credited as your plans develop.

Alternately, if you get a 30 day visa on arrival in Bali the chance is good that you won't be asked for your onward ticket. Then you can get another 30 day extension through an agent in Bali. It costs about US$75.

You are right Marmot they are not accepting anything other than an exit ticket

You have said that after Flores you're going to Laos so I presume you have a ticket for that sector of your travel right? That should be enough proof for the Indonesian exit requirement. If you don't have a ticket yet then get one.

Hanuman, I supplied all, the ticket to Laos, Laos to Bangkok, Bangkok to Yangon, round trip from Canada and they still refused.
"Thank you for the airline ticket, the Consular Services also need the airline ticket leaving Indonesia to Bangkok".
In our 10 week itinerary the only portion we haven't determined yet is the exit from Indonesia.
