Welcome to the forums, Goesti!
The forums are not really a place to just start a new thread and post a Q expecting people to offer advice.
If you're planning a trip for 2017, then you have plenty of time to read through the forums. I learned more than enough on just 2 weeks.
Start off by browsing the blue "Wiki" threads at the top of the threads list and then pick different threads to read through based on relevancy. Threads on the different credit cards are a good place to start. The thread about Bluebird will teach you how to hit the spending threshold to get the big CC signup bonuses without spending a lot of actual money. And many more...
Good luck!
