I am trying to book a flight on Allegiant Air for DH, myself and LO and I am a bit confused. If I put her in under children it charges another $80. and it prompts me to pick a seat for her. It isn't making much sense to me because for a full roundtrip ticket for each of us it is $195. So if you purchase a seat for an infant it costs less? What I was planning on doing is holding her on my lap, so does that mean I do not even put her in when booking the ticket? That just doesnt seem right to me, but I am not sure.
