Hi - We are leisure travelers. We used to fly United quite a bit but have not for various reasons for some time. Am looking at flights from Boston to Palm Springs or Ontario and United flights work for us. Looking at various review sites like Yelp and such, the reviews are less than stellar! However - I think the frequent fliers here are the real experts.

Are those reviews just the bad samples or is United really that bad? We will be flying main cabin. I am mostly interested in reliability.
Thanks so much.
