Boston Logan has maintained its abysmal record of uncleanliness in the women's restroom opposite the Delta Airlines boarding area. On a recent trip, as on a previous one in the fall of 2014, this restroom had dirty toilet stalls and nonfunctional "automated" sink handles. The airport is, in general, user-unfriendly. Yesterday I had intended to wait for a friend on an arriving flight in the cell-phone lot, which I'd not been to before. The signage to the lot was so confusing that instead I ended up in the central parking garage. Signage from the garage to the US Air arrivals area in the terminal was similarly unedifying; I had to ask an employee for directions. Same thing to navigate the return to the garage. The signage for the terminals and parking is not only confusing but also dangerous: any attempt to change lanes runs the risk of involving oneself in a crash with one of the numerous fast-approaching vehicles on one's tail. I always dread having to pick up anyone at Logan and often resort to telling visitors they must take a cab.
