I am an anxious flyer (I always have a xanax 30 minutes before scheduled departure) and I can't add rushing to the airport to a trip. I would be a mess. So we always plan to arrive 2 hours before departure. For 90% of the flights this is wasted time, for the other 10% when sh*t happens (you know when you leave your passport at home, or the water main breaks on the only road to the airport) you have time for the unexpected delay. Last month in France, I misread our electronic boarding passes. I thought that our flight left at 12:30 and was shocked to see 11:20 on the pass. So on the morning of our departure, we got up on hour earlier than planned, took the metro to the airport and (of course) breezed through checking our bags and security, only to discover that our boarding time was 11:20 and the flight actually departed at 12:35. (reading is fundamental). So now we had even more time. But I knew that I had my Priority Pass and lo and behold, there was a lounge in our terminal. So we walked over to see if I could get the two of us in (my husband didn't have his PP card). The answer was yes. We spent a lovely couple of hours in the lounge, had breakfast, charged our phones and other electronics. It was quite relaxing and a great way to spend the time. No regrets there.
Another time we were traveling to Indiana with my mom. I told her that we would pick her up at 10am for a 1pm flight. It's only a 30 minute drive but my mom has never, ever been ready to leave when we pick her up for anything. (I'll knock on her door and she will meet me in her PJ's "Oh, I overslept", or she will say "I still need to walk my dogs". Every.Single.Time.) So we just add an extra half hour when we go anywhere with her. This time she really pushed back because she is the kind of person who wants to walk up just as the plane boards. So she refused to go with us and said that she'd take an uber. Fine with me.
We got to the airport at 11:00, went through security, then headed to a restaurant for breakfast/lunch since we were flying Southwest (no food). My husband and I had a lovely meal and some drinks, and the whole time I was looking for my mom. She arrived, totally frazzled at 12:25. She was thoroughly angry at TSA, plus ravenously hungry. She had the uber pick her up at 11:30. She got to the airport at noon and without checking her ticket went to the weird Southwest gate in SD that has two gates and it's own TSA line. (In 20 years we have used that gate twice - the rest of the time is the main gate area). She didn't tell TSA that she had a knee replacement so she set off the alarm and had to have a pat down. Then she got through and discovered it was the wrong gate. Then she got to go through TSA again at the other area, lol. She was livid when she found us - it was all someone else's fault! - and had to quickly buy a salad and eat it on the plane. Her demeanor continued into Indianapolis when the only place open at the airport was McDonalds - "I don't eat McDonalds" - lol. You are eating that today, mom. But it hasn't changed her behavior. She will be a "last minute Lucy" until the day she dies. And of course, I will probably continue to be an early-bird. I wonder if there's a connection?
