United Airlines We had a great vacation planned that was ruined by United Airlines. Albuquerque Nationwide

It was going to be a great vacation.  We had a united flight to Montreal, a railroad trip to Quebec City, and another flight back home.  Originally, we only had to change planes once.  I asked for special seating and priority boarding because I have bad knees.  Of course everything was an extra charge in addition to the airfare and we had to pay extra because we had luggage.  Then came the changes.  Those flights were cancelled and we had to make 3 stops and 2 plane changes to get to Montreal.  Of course extra charges.  When we got to the airport the kindly United agent rearranged our flights for us so we only had to change planes once in San Francisco.  Of course we lost our priority boarding and preferential seating.  Supposedly, all the "extra" charges were refunded.  Who can tell with the mountain of paper, with the special codes. 

The first plane was so small, (we used to call them commuter jets), and we were in the last row with our knees in our faces, right next to the bathroom.  No reclining, no standing.  It was most uncomfortable.  In San Francisco, nobody could tell us where to find our next plane.  Only that we had to go to the next terminal. ("Just follow the signs", they said.)  What signs.  Finally we stumbled across an Air Canada employee that pointed us in the general direction.  Again with the rear seats and the small plane.  Of course they had to tinker with the tickets.  When we left Quebec City for Toronto via Air Canada, everything went smoothly.  When we tried to connect with United in Toronto we couldn't.  It was delayed, and delayed, and delayed and finally cancelled.  The Air Canada agents were really nice and finally got us booked to Albuquerque via Denver.  The plane was bigger and more comfortable.  Then when we connected with United in Denver it was the tiny plane again.  It took 22 hours to get home thanks to this air-thief company.  If I ever fly with them again, it will be too soon.  They have stolen my last dollar.
