I've had a few oddities lately with Flighty:
1) We were flying DL out of PVR on 12/14/24. It tracked our incoming plane as having landed at Gate 7 (with maybe an hour before the flight departed). But our flight left out of Gate 12. I'm pretty sure they did not have time to get everyone off the plane at Gate 7 and then move to Gate 12 and start boarding within 30 minutes (since boarding started like 35 minutes before departure).
2) I had a DL flight from DTW to ALB on 12/28. Was showing us as arriving late, but we arrived 20 minutes early. ie: live tracking showed one thing, but the other section showed something completely different. I figured it would've updated, but it never did until maybe 10 minutes after we landed. (I had WiFi connectivity during the flight).
