We're going to the airport in Atlanta next Friday and am wondering how far in advance we can reserve a car? Thanks.
When to request a ride
The Guru Take
30 days for Uber. 7 days for Lyft.
You can request a ride up to 30 days for Uber and 7 days for Lyft (as of 2017/08). So you should be good. Taxis and Limos can also book you a ride, and those companies all have different policies.
...but for next Friday, you should be all good.
