Thanks.
Going over we are flying to Helsinki for five nights. We will ferry to Tallinn for a day trip or an overnight. We will train to St. Petersburg.
The cost we see is the 144 Euros or a little over $200. Second class is 50 Euros less. Is First Class that much better?
Coming back we will fly out of Moscow. Depending on whether we are with Delta or another airline at that time, we will have some stopover options. WAW could be among them as could Paris, Amsterdam and several German cities. Will know more after September 5.
