I am trying to get 5 tickets from KC to Montreal on June 7 or 8 and 3 tickets from Boston back to KC on 16 or 17. I have about 125K United Miles, 300K AA miles and 250K Amex Points. Would like to fly United to get the economy plus seats up to Montreal but, unfortunately there only awards are 25K per ticket. Can I use use the 25K to get a roundtrip for 3 of the tickets coming back from Boston? It seems I have to call United to do this and it will be $25 per person. I could do AA but I really would have to get one first class ticket for my father in law. Any ideas would be greatly appreciated!
