| I am writing on behalf of my co-traveler/wife and myself regarding terrible and unbelievable experiences we had with United from Prague to LA via New Jersey EWR, on July 23, 2019. The first and second legs of our flights were with Austrian Airlines (OS 0082 and OS 0721) on July 11 and 15 which went through without a hitch and in most courteous and professional manner by Austrian. The third leg was with Czech Airlines (OK 079) on July 19 which again was also completed without a hitch. However, the fourth and fifth leg of the flight (UA 0187 and UA 2394) on July 23 were total disasters. In Prague airport, we were told that due to weather conditions the flight would be delayed approx 7 hours. Having given no other options for other United flights or otherwise, we had to wait out the delay and board the plane about 7 hours later. In New Jersey, having missed our connecting flight to LAX, again without any other options given by United, we had to stay overnight in Ramada Plaza Hotel (a virtual dump of a Hotel) for about 4 hours before returning to the airport for a 6am standby! Although vouchers were issued for the hotel (United's choice) and some food, we had to take a cab at our expense to the hotel, as no vouchers were provided, and it was very late at night. During all the interactions with United employees, customer service, supervisors, and hotel crew we were treated unprofessionally, rudely, nonchalantly, carelessly, and aggressively. At all times, the attitude of the United employees was insulting and such that they couldn't care less about our dilemma, and that they had heard these sort of complaints a million times before, that it is what it is, and basically take it or leave it. Beside suffering the aggravation and stress, the above delays, totaling a whole day, caused tremendous backlash for my wife and I, as we are both professionals with appointments and commitments to meet (which we missed), having counted on the on-time arrival in LAX. We could not even spend our food vouchers due to lack of time, and United flight crew denying our vouchers for food on the plane (EWR to LAX), and the Mexican Grill denial of vouchers in the food court of LAX arrivals. The way we see it, United has received its full payment for the tickets, but we have not received the full service promised nor have been compensated for our losses suffered. To say the least, improper actions or non-actions of United have bitterly ended a much-anticipated joyful vacation. If you have a choice, avoid United, and spare yourself lots of heartache.
