I'm planning a trip to Poland in September. Ryanair are offering an excellent fare with a decent departure time. Only dilemma is that the return flight is scheduled to come in at 19:05, and my last train home is, I believe 20:47. This would be nice, though, as it effectively gives me a free extra day in Warsaw. I know it's not a massive airport, but I also know that there are always queues to get through immigration. Is 1:42 cutting it a bit fine to land, get off, clear immigration and get to the airport? If so, I'll consider another route.
