In a few weeks we will be taking car service from Queens/Brooklyn to LGA. I have a few questions mainly about luggage. How does curbside checking go about? Whats the difference between curbside & going up to the counter? Are we allowed to lock the suitcase or keep the lock open & they lock it for you? What happens if we take an empty suitcase and check it in? Is the Delta terminal in the same building as the main terminal? Are there bathrooms inside the terminal once you go past security or would you have to go out and then go through security again? What about the restaurants inside Delta terminal? We are going from LGA to MCO. Does Delta show movies or serve sandwiches/something to drink? How do you guys cope with going up and coming down to make your ears pop?
