Dear all, we are planning to fly to Japan from Europe using companion ticket in business/first class and this will be right after our little one turns 2. Hence me and my husband are not sure how to proceed - whether we can book one of us in Economy and get 2 business tickets for adult+toddler and then just have our 2 year old sit on our lap in Business. Or whether airlines would be very strict on not allowing this. Any feedback is welcome.
