We Lyft often. They have the XL with plenty of room for luggage. Think van or large SUV. Mears will want to pick you up super early, as much as 4 hours before your flight. They do have other car services outside of Lyft and Uber (we rarely use Uber).
Here’s a link to a thread here about it. This should be relevant. But you can always ask questions to get the thread bumped up.
But if Mears gives you peace of mind, it’s just a few hours. It won’t be the end of the world. Just plan your morning accordingly.
