In May 2010, Lunney's travel expenses caused controversy as part of an ongoing debate regarding MP expenses. The "Times Colonist" reported that Lunney spent $169,935 in one year travelling between Nanaimo-Alberni and Ottawa. In his defence, Lunney stated that despite the trip being long, he returns to his riding at "every chance I get" to attend events and meet with constituents. Lunney defended his regular business-class flights, stating that because he works en route he needs the extra space to allow him to work on sometimes confidential material on his laptop. Regarding his wife accompanying him, he stated: "I sometimes also encourage my wife to come along on these trips because I wouldn't have much of a chance to see her if she didn't, but it's allowed according to the rules on spending and she travels in economy class."
