( CNN ) Another flight brings another complaint about an airline interfering with a passenger breastfeeding her baby . The mothers who complain about instances of airline employees interfering with their breastfeeding or pumping are n't covering up and going away ; they are tweeting out their complaints in 140 characters or less , sometimes in multiple posts , other times taking pictures of longer reports . Kristen Hilderman is the latest mother to say she was hassled while breastfeeding . The Vancouver mother was returning to Canada from a vacation in Costa Rica with her family on Sunday night when , she says , there was a problem on the final leg of her trip . Hilderman was feeding her 5-month-old son on board United Airlines Flight 438 as the aircraft taxied along the runway before taking off from Houston to Vancouver . To describe what happened next , she took a picture of her typed recollections and posted it to Twitter . `` A male flight attendant named Keith walked up to our row and said to my husband ( loudly , so that everyone around could here ) , 'Are you two together ? ' '' Hilderman wrote . When her husband said yes , Hilderman said , the flight attendant `` tossed a blanket at him ... and said tersely , 'Then HERE , help her out . ' `` When she twice asked what he was supposed to help her out with , she said , the flight attendant ignored her . Passengers on the plane were supportive , she said , and told her they had n't known she was breastfeeding until the flight attendant singled her out . `` I 've been breastfeeding my son in myriad public places since he was born , and never has anyone made me feel so uncomfortable and ashamed for feeding my baby without putting a cover over his head , '' she wrote . United Airlines spokeswoman Jennifer Dohm said that the airline reached out to Hilderman on Monday night via Twitter and that airline officials `` look forward to speaking more with her and to our crew member to understand what happened . '' `` On our general approach to breast feeding , we welcome nursing mothers on board and we ask that crew members do their best to ensure their comfort and safety as they do with all customers , '' Dohm wrote in an email . `` We also ask nursing mothers and passengers seated near them to be mindful of one another 's space and comfort . '' Hilderman , who filed a complaint with the airline , said United had not contacted her beyond their tweeted reply but said she has found support from allies on social media . Why are we so squeamish about breastfeeding ? Delta passenger Lauren Modeen , who needed her breast pump on a January flight but was forced to check it as luggage , started a Boobs on Board Facebook page that 's gained over 1,100 followers in the past month . `` Before social media , the majority of these harassment stories went unheard , '' Modeen wrote in an email . `` As a result , airlines faced little pressure to improve and pave a better way for mothers and children . '' She wants her Facebook page encourage airlines `` to publicly post their explicitly clear pro-breastfeeding/pumping policies inside every airplane so the rules are not left to interpretation by an airline employee , and in turn harass/shame/bully a mother . '' United , Delta and other major U.S. airlines say breastfeeding is allowed on their aircraft , although United does n't post its policy on the airline website . American Airlines , Southwest Airlines and Delta Airlines do . Though you ca n't please everyone in the air , women are allowed to breastfeed in flight , says veteran flight attendant and author Heather Poole , who is also a mother . `` Which means if breastfeeding bothers you , maybe try looking away , closing your eyes , '' said Poole , author of `` Cruising Attitude : Tales of Crashpads , Crew Drama and Crazy Passengers at 35,000 Feet . '' And remember that baby could be crying instead , giving you another reason to complain . `` Better a happy baby than a crying baby . ''
United says officials `` look forward to speaking more with her and to our crew member '' who is a U.S. citizen of Pakistani descent -- about the incident.''
