Orbitz will ticket your exact itinerary as one itin in USD.

Orbitz also has several options that are $400-500 cheaper and only about 3-4 hours door-to-door longer. (Just looking at one-way fares...)

Was your agent quoting something far below what Orbitz's prices are? I trust Orbitz (even though I'm not a huge fan of travel agents unless you really, really need them)...and they can get you there in about 28 hours for just over $1,000. Or your itin for $1,500-ish. That's a pretty good deal overall...I'd be hesitant to book with someone who seems to have difficulty booking this just to save a few bucks.

And I'd never, ever, under any circumstances book with a human travel agent that doesn't have 24/7 service.
