Is there enough room for 4 people and 4 luggage to airport?
The Guru Take
Depends on the size of your suitcases. Make sure to order the right sized vehicle.
Uber and Lyft's regular services (e.g. UberX, UberBlack, Lyft, etc.) will dispatch you a four-door sedan, and they are desigend to transport up to 4 passengers. If you called one of these, you would be limited to the trunk to stow all of your luggage. If you feel the trunk is enough, you may be able to get away with it. (Remember that vehicles approved for UberBlack tend to be larger than the ones often used for UberX.)
Our recommendation, however, is for you to order an SUV. This would be under UberSUV, UberXL, Lyft Plus, etc. They are designed to hold 6 or more passengers. Here's an example list of cars that may show up when you request a SUV.
UberSUV approved vehicles
Cadillac: Escalade ESV
GMC: Yukon XL
Infiniti: QX56, QX80
