Coincidentally, I will be flying this round trip tomorrow morning. While I can't speculate on what loads will be like in July, I can answer any other questions you may have on my experience tomorrow, both going and returning.
One nice little perk on the International stuff is that you will receive our Direct TV service for free during the first half of the flight (or the last half coming home) - but when we're over the gulf, we lose the service.
Hope you'll give us (or Apple?) your business. Either way we'll be glad to have you.
