I'm finally taking the fam to Washington DC next week. We're flying (first time for the boys), and I was wondering if anyone could offer hints re: supplies on the airplane, if he qualifies as AWD (Americans with Disabilities) "perks", etc. We're not renting a car, just relying on the Metro (which makes me nervous if we'd need to find a dr/hosp fast). Staying in Crystal City. Main concerns include first time flying with Carter, our T1D. Any ideas/hints would be appreciated.
