I've booked flights for Portugal and Poland. Following the Poland home game, I'll fly to Lisbon the next day, ensuring I have enough time to reach the match venue. The return journey is a bit tight, but the flight is scheduled for late afternoon on Monday. After the Croatia home game, I'll fly to Warsaw the next day, providing ample time to reach the match venue. However, the return on Tuesday morning may be problematic if, by any chance, the match isn't in Warsaw, though it typically is. I've opted not to book for Croatia yet due to their frequent venue changes and uncertainty about transport links. I'll wait until the venue is announced before making any arrangements.
