777-300 Polaris v. 777-200 first?
We have the option to fly United SFO-LHR in either 777-300 Polaris or 777-200 first and we're not sure if someone recommends one over the other and why. Are the seats more comfortable in Polaris? We'd love to hear what anyone has experienced on both. We're a couple so we would like to sit and talk to each other if one is better for that as well.
Thanks!
