My husband and I were supposed to flying with our twin 18mo daughters in two weeks but it's looking like he won't be able to make it. We were going to fly with the girls as lap babies, something daring on such a long trip (though we have done it when they were younger) but we just can't afford the extra seats. I am afraid I might have to book at least one extra seat since I can't have two lap babies, but I want to know if there are other options. Is it possible to find someone who is booked on the same flight and have my child added to their ticket, or is this ridiculous?

Has anyone been in this situation before?
