This was our 3rd 2-4-1 and by far our most stressful to book. In the past I looked at availability and based our trip around that, booking both legs myself. Those were off season trips, and this was for next April/May when reward seats in F were much scarcer. Not only did we end up booking outbound first with agent assistance on the return but we ended up flying from/to alternative US cities. Which is ironic, because we started flying BA originally because they were the only International airline flying direct to Europe from San Diego and we were tired of flying out of LAX. But our certificate was expiring and we didn't want to waste it.
