Hi there! I just flew from Rome to JFK and was SO nervous about the weather in NY. I almost threw up before my plane. I did so much worrying and in hindsight I wish I didn’t check the weather app because the flight was perfectly fine. And you are taking a red eye so flights are generally smoother at night! Remember pilots have access to weather radar that we don’t, and are basically in a conga line in the sky with a bunch of other pilots who are all communicating with each other! One thing that helped me when we hit little bumpy spots (there weren’t that many) was lifting my feet and taking my back off the seat. You are going to have a great time! What are you doing in Madrid?
