Traveling now

...is much easier! Gaia doesn't escape, waits more or less patiently in queues, jumps with joy into the plane by herself. Eating is not a problem: she can grab a biscuit or an apple and can easily survive until a proper meal. There are however bad sides of this phase too - it's almost impossible to keep her sitting with a belt on while taking off since she wants to watch! (putting a belt is anyhow another story). And she is so curious that she refuses to sleep! At least I do not need to run around a plane. 
She threw me a big tantrum once while collecting a suitcase but all in all she is a great travel companion now.
