My family and I flew from Zurich to Rochester NY in July 2017 and this was our first time with United Airlines and was pleasantly surprised at the level of service and leg room we found with United Airlines. Considering that my husband and son are both 6ft plus they had enough and more leg room in economy class.
As well their food and entertainment system was relatively good. We were well taken care of food wise, they kept bringing water, drinks, snacks and gave us 2 meals on this trip.
The hostesses and stewards were all pleasant and well mannered. Overall I would rate 4 stars out of 5 for United Airlines so much so we have another trip coming up in 6months and are only looking at booking with UA considering our lovely trip with them.
They were so attentive that when my daughters entertainment system didn't work and they could not move her or fix it they said that they were happy to compensate her once we get back home!
I would highly recommend UA in comparison to many airlines out there these days!!
