On Monday night I was at the airport on none Uber/Lyft business. Although I never queue at the airport, it seemed really busy with arrivals and since I was already there I decided to queue. I entered the lot at 5:51 pm, I was 23 for Uber and 99 for Lyft. In 17 minutes I got an Uber request, and I was still 50 for Lyft. Looks like Lyft has twice the business at the airport and four times the drivers (at least at this time).
