I like flying from LCY despite the fact there is no lounge and the boarding pens are bit EZ @ AMS (& LYS?). You're in and out in a flash and you're flying with frequent flyers so no annoyances on that front.
Getting there, I usually take the car and pay through the nose. Does anyone out there travel down the Liverpool St line to Stratford and then Jubilee/DLR it to LCY? Is it faster than LST-Bank-LCY? I'd really appreciate it if anyone can respond on that.
