We arrive at IAH, 4:30 am. We have no where to go at that time, and need to wait on the rest of our party who is arriving 5 hours later. My question is....if we do not claim out luggage at 5 am, will the airline hold it for us for 5 hours? Will they store it? Can we request this? If we go claim our luggage at 5 am, we will be outside security and unable to get back in. There is no where to sit for 5 hours outside security.
