The Galveston airport has tried to get pax flights, but no airline will do it with Hobby being only 45 min. away. The airport director actually had this question come up this past week.
Trip: I think the number of people will be about the same....when Oasis comes in I think Disney will probably leave. I also think that that is part of the marketing strategy. Neither CCL nor RCI want DCL to get a foothold on the Texas market. Also I would anticipate Oasis embark/debark days to be on Saturday so overall there will be fewer people per day than there is now with both big ships embark/debarking on Sunday. A win/win for both Carnival and Royal Caribbean.
