TripAdvisor has defended itself against accusations of misleading travelers by failing to stop some of its highest ranked hotels winning their status with fake reviews.UK consumer group Which? Travel analyzed a total of almost 250,000 reviews for the 10 top-ranked hotels in 10 global tourist destinations, from Las Vegas to Cape Town. It found that one in seven of the hotels had "blatant hallmarks" of fake reviews, with others raising "serious concerns."But TripAdvisor called the analysis "flawed" and said its more sophisticated detection tools were able to weed out fraudulent feedback.Which? Travel said that when it reported 15 of the worst cases to TripAdvisor, the reviews giant -- now one of the world's biggest travel websites -- admitted that all but one of the hotels in question had been caught using fake reviews in the past year.Six had previously been penalized, and two had received a "red badge warning" -- where TripAdvisor warns users that the hotel is suspected of using fake reviews, and has "repeatedly failed to remedy its behavior and refuses to cooperate with TripAdvisor's investigators."Yet, Which? Travel said it found that the review patterns had continued unabated despite the measures, and the red badges had been removed.The group has accused TripAdvisor of a "lack of serious ongoing action to address repeated abuse of the system."It says that five-star reviews left by new users who have written no other reviews should be a red flag. Its analysis compared the proportion of first-time five-star reviews with that of first-time three-star reviews, which are less likely to be faked.In total, it studied 247,277 reviews."TripAdvisor's failure to stop fake reviews and take strong action against hotels that abuse the system risks misleading millions of travelers and potentially ruining their holidays," said Which? Travel's Naomi Leach.TripAdvisor has removed hundreds of reviews in light of the investigation, Which? Travel claimed."Striking" evidence of fake reviewsHotels in the Middle East had "striking" amounts of fake positive reviews, according to the research. TripAdvisor docked 730 five-star reviews of the "best" hotel in Jordan following the analysis -- but the hotel has not been given a red badge. It remains in the top 10 in the country.At the top-ranking hotel in Cairo, 79% of five-star reviews came from one-time contributors. Just 14% of three-star reviews came from similar accounts.The hotel has lost its status as a result of the reviews' deletion.Las Vegas was another hotspot for fake reviews. At two of the top-rated hotels, almost half the five-star reviews came from one-time contributors. For a competitor which did not arouse suspicion, the figure was just 3%.Some of the top-ranked hotels in London, Paris, Barcelona and Cape Town "gave reason for suspicion," the research showed, but failed to demonstrate the same patterns across the board.Repeat offendersTripAdvisor called the analysis "based on a flawed understanding of fake review patterns," adding that "it is simply far too simplistic to assume all first-time reviewers are suspicious."It said that Which? Travel did not have access to IP [internet protocol] information or location data, both of which TripAdvisor uses to detect fake reviews."We analyze hundreds of data points about each review -- most of which only we have access to -- and we combine that data with a wealth of knowledge and understanding of review patterns that our team of experts has gained from tracking hundreds of millions of reviews over a near 20-year period," said the company."This includes an ability to track and analyze first-time reviews in far more detail and with far more rigor than Which's team was able to do."Online reviews influence an annual estimated ￡23 billion ( billion) of booking transactions in the UK alone, according to the UK government."Sites like TripAdvisor must do more to ensure the information on their platforms is reliable," said Naomi Leach."If they continue to fall short, they should be compelled to make changes so holidaymakers are no longer at risk of being duped by a flood of fake reviews." 4152

The United States Postal Service (USPS) and their unions continue to raise an alarm about their dire financial situation. According to the USPS officials, they are losing around billion per month amid the COVID-19 pandemic. A recent release said the financial situation is “threatening their ability to operate.”The problemWhile package deliveries are up, business mailings are down, which is how USPS makes most of its money. "It is a dire situation, Mark Dimondstein, president of the American Postal Workers Union, said. "The post office does not run on any tax dollars; it runs on the revenue generated by postage and postal products."Dimonstein says the postal service could run out of money by fall. Bailout? USPS has asked Congress for a billion bailout. While a billion funding package has passed the House, it has so far not passed the US Senate. The American Postal Workers Union has launched a rare television advertisement asking Americans to call Congress. 993

The paraplegic head football coach for Independence High School is claiming he was forced to "scoot down the aisle [of a plane] on his butt" and off the plane after United Airlines denied him an aisle chair on multiple flights.Tyler Schilhabel was injured in an ATV accident years ago and is disabled from the waist down. According to Schilhabel, he and his wife Courtney were traveling via United Airlines to the Dominican Republic for their honeymoon. Schilhabel says he booked his flights through Costco's travel program, and was scheduled to travel from Los Angeles to the Dominican Republic with a connecting flight in Chicago. The Schilhabel's were also scheduled for the same route coming home. According to Schilhabel, when they landed, the plane did not have an aisle chair to transport him off the plane. Schilhabel says his wheelchair is too big to fit down the aisle of a plane. Schilhabel says United Airlines also did not have a ramp or elevator to help him off the plane and only had stairs. According to Schilhabel, he had to scoot down the aisle "on his butt" and then had to hop down "step by step" to get to his wheelchair. Then on the Schilhabel's connecting flight in Chicago after the honeymoon, United Airlines also did not have an aisle chair. This time, Schilhabel says he and his wife had seats in the back of the plane. Schilhabel says he had to "scoot all the way down on my butt." On one of the flights, one of the flight attendants picked Shilhabel up and carried him down the aisle so he could catch his connecting flight. When 23ABC spoke to Schilhabel, he called the whole experience "humiliating."Schilhabel says on his last six flights with United Airlines, they were either "late with getting an aisle chair" or did not have an aisle chair. He also claims this has happened to his friends as well, some of whom are disabled veterans.According to the U.S. Department of Transportation and the Air Carrier Access Act (ACAA), it is illegal for airlines to discriminate against passengers because of their disability. The Department of Transportation says airlines are also 2118
