Yes, but look at BA, AF, and LH at ATL. BA tried double-daily, failed. LH is 6x a week, and on thier smallest trans-Atlantic aircraft, an A340-200. AF has the DL codeshares. Also keep in mind, Swissair and KLM dropped ATL this past September. Varig didn't survive either. Austrian left, so did Sabena. Compare the selection of international airlines at major hubs like ATL, IAH, DTW, and DFW to cities with smaller "specialty" hubs, like MIA and SFO, or no hubs, like BOS, and it's dissapointing.

Newark and Chicago fortress hubs are the exceptions thanks to the huge size of both.
