I have low-level J award tickets for a trip to Europe this summer. I didn't book a lap infant ticket when I booked the award tickets because I thought I might use GUCs instead. Now that I've realized the prices for Y tickets are a bit too expensive for the travel dates (or any dates during the same month), I called the DM line to ask about the price of adding the lap infant. I usually check the KLM website to get a rough idea of the lap infant fees before calling, but I couldn't generate a revenue itinerary with the exact same routing in this case. Similar routings were pricing around $7000 in J so I was dreading the call. The agent quoted me about $65, the exact price of the taxes. I asked her to confirm, which she did, and I then asked her ticket it. She promptly disconnected me (although she couldn't bypass the survey question, left her a 1). HUCA...

Agent #2 spent a lot of time doing calculations and quoted me $2100 for the same lap infant ticket. I asked for a supervisor given the large discrepancy between the two figures. He was really nice and contacted the international desk, who came back with a price of $15. This sounded way too cheap, but I asked him to ticket it. I was e-mailed an e-ticket receipt showing the baby in the J cabin, and he attached it to my reservation (so I can see the infant under my itinerary online). Everything looks correct.

A few times in the past I've used GUCs and the lap infant ticket was priced on the original Y ticket (without upcharge), but those tickets were always at least $100. For those with more experience with lap infant fares, am I likely to have issues at the airport or did I just get lucky?
