Thanks everyone for your responses. I am an international traveller and therefore there is absolutely no way that I can not check in bags. To the person who said what day of the week it will be a Tuesday, a weekday, and be in rushhour, unfortunately. We will be flying into LGA on a US Airways flight operated by Piedmont from Philadelphia. But before that we are flying from Newport News to Philadelphia, those are a connecting flight. So I don't know if we would be able to get our bags checked all the way through?
