Should I work for an exotic tech startup company?

You don't need to worry about it until you graduate with your degree. It would be a good idea to intern for one of the inflight Wi-Fi companies while you are still in school, as that should help you make a more informed decision.

If you are married and especially, if you are married and have children, you should work for an established company right out of school, as the medical benefits, compensation and workplace stability will be better. Even if you are not married with children, you should be careful about getting your first job at a small, young company whose primary business could be derailed by regulatory issues. 

It is possible that one or more of these companies developing in-flight Wi-Fi services could be bought out by Juniper, Cisco, or even a major airline.  The scenario of the airline purchase is interesting and has precedents, e.g. American Airlines purchased SABRE. Even if such an event should occur, I don't know if it would have any benefit to you as employee rather than a founder/equity owner.

Another reason to work for Juniper or Cisco for a few years, when you first graduate, is that it will increase your credibility and perceived value to future employers. Transitioning from a big company that is well-established in its industry to a start-up is easier to do than vice-versa. My first job out of school was at an innovative small company; I left after two years to work for IBM. I wish I could have done it the other way around.
