...I need some help figuring out the best route for my upcoming trip. My wife and I would like to visit one of our friends in Moscow this coming spring. We had originally planned the following: ORD - LHR LHR - HEL HEL - Moscow via high speed train (maybe a one night stop in St. Petersburg) DME - LHR LHR - ORD (could alternatively fly to CDG and spend 1-2 nights there before departing to ORD instead of LHR) Leaving on a Tuesday afternoon and returning 12 days later on a Saturday. Price was around $1200 per pax for airfare only.... We've since thought about swapping HEL for VIE and maybe doing a one night trip from Moscow to St. Pete via the sapsan train. Ideally we'd have 48 hours in LHR (visiting friends) in either the tail end or beginning of the trip. We'd also like to be in Moscow for 4-5 nights. I think we'd need at least 2 nights in Vienna to see the sites, maybe 3. St. Pete would be nice but an expensive side trip both in money and time. That being said, I am having trouble figuring out the best flight plan. Any tips or suggestions? Would prefer to stay on *A but would jump to an alternate airlines (SU, easyjet...etc) if the price is worth it. Thanks in advance for your help...!
