Curious if I fly avelo (I never have - but they have super cheap flights out of RDU) - and I don't choose a seat- will they separate me from my 3 year old? I could pay $35 total for the three of us to guarantee we are together - which I have zero issue doing, but that is the way back of the plan and wondering if we don't choose if there was any chance of getting closer to the front and still be together?
