I booked a ticket over the phone a couple of weeks ago, and after I looked at my itinerary online, I noticed that my name appeared as <firstname> K <lastname>, as opposed to my actual middle initial of L. I called in and tried to get them to change it, but the person I spoke to said that after it was ticketed, there was no way to change that without canceling the ticket and re-issuing (and probably losing my upgrades along the way).

So, a few questions:

1. Is this really correct -- they have no way to change the middle initial?

2. Will I run into potential problems flying internationally? Presumably the points that might cause problems are at security and at check-in getting my boarding pass... (I'm flying from the US to Singapore via NRT one way and via HKG the other)

Thanks! I'm really kind of irritated, since it's so clearly the reservation agent's fault, the two keys being adjacent and all that.
