Something similar I tried to do a few years ago. I bought my brother and his then girlfriend (now wife) with airmiles flights to St. Lucia from GLA (they got engaged in St. Lucia) one Christmas. I really wanted the old style tickets but they had done away with them so I printed out the e-ticket and bought a model BA plane. I put the e-ticket inside the box so they knew it was a flight they were getting instead of a plastic aeroplane model .

It's nice to know I helped them on there way .
