I do uberxl in nyc plus Uber family which I have to carry a car seat assigned by uber. A passenger came back from vacation and he was traveling with his family (4 passengers total). To my surprise each one of these passengers had 1 extra large bags with them (they definitely had to pay extra fees to get them on their flight). Mind you this pax ordered a uberx. In my mini van I hardly was able to fit all 4 bags. So I proceeded to write a letter to uber stating the current situation after the trip was complete. And they need to revise the fare and upgrade that passengers uberx rates and upgrade it to uberxl. Just to let you know when you pick up somebody from jfk airport, port authority assigned a specific parking lot for Uber drivers to wait for requests, in turn Uber places you on a queue which the average wait time is about 2 hours to get a request to pick up a pax. This is their response... "Sorry to hear about the hassle of transporting all the extra items on this trip. I understand how this could be frustrating. Riders are allowed to bring items along at no additional charge if the items fit into your car. While we don’t have a limit to the luggage or items riders bring along like we do with the number of passengers, we do ask riders to ask permission before transporting extremely large items — we know you work hard to maintain the quality of your car. If you aren’t comfortable taking particular items or if you don’t think the items will fit into your car, some of the things I recommend doing are politely asking the riders to cancel and request the appropriately sized vehicle, or offering to make two trips, making it clear you’ll keep the trip going the whole time. If you have further questions how to best handle situations like this, I’ll be happy to help." GUBER ON!
