I will be in Lviv, but am booked on a Chernobyl tour so would want to arrive in Kiev the night before. I have the option of taking a Ukraine Airlines flight from Lviv to Kyiv, or a Motor Sich airlines flight, both departing Lviv around 5 PM (17:00). Which one is better? Or should I just take a train? The trains leave around 4-6 PM (16:00-18:00) but they arrive rather late after 11 PM (after 23:00). I have reserved a hotel near the train station.
