Can I pack a Synapse 25 inside an Aeronaut?
I've had the Synapse 25 for almost half a year now and taken it on quite a few trips. I absolutely love the thing to death :)
Anyway! After realizing how much space my laptop takes in my backpack, and also considering not checking luggage and instead having anything extra mailed by post (to avoid loss during multiple connections), I've decided that the Aeronaut might just save the day. However, the Synapse 25 looks a bit big to carry-on as a personal item, so my question is whether I can fit it inside the Aeronaut, and then pack that.
I've done some searching and found a thread where someone took a photo of a Synapse 19 just about fitting inside an Aeronaut, so I'm worried the 25 won't fit, or would require deforming the back foam panel somehow.
This'll be for a year-long trip to Thailand (where I will be teaching English) so there's no way I can pack all I need in just the Synapse 25. And I've got two connections with about 2 hours at each point, so I'm worried the luggage will be lost somewhere in Vietnam or Bangkok.
Thanks for any help or suggestions!
edit: While I'm asking about the Aeronaut - I'm also wondering whether the Guide's pack is possible to carry on (in the overhead compartment), and whether there are plans for a hip belt addition?
