American low-cost carrier , Spirit Airlines , has just acquired its 69th plane and has found an interesting way to celebrate . Not only has the airline slashed roundtrip fairs to £69 in April and May - including taxes and fees - but they also announced such a drastic price drop with some rather cheeky copy . The emails sent around announcing the sale reference a particular sexual act in very blatant terms , with some customers complaining that the new campaign is in poor taste . Scroll down for video . American budget airline , Spirit Airlines , is celebrating it 's 69th plane with low fares and cheeky ad campaign . 'We 've been waiting to hit 69 planes for years , ' Spirit 's website reads . 'It 's our favorite number -- ever since we were twelve and found that magazine under our brother 's bed ( the one with the fantastic articles ) . ' # 69 is perfect : just the right size , with a cockpit that 's in your face ( because it 's bright yellow ) . 'Use your mouth to spread the word : Spirit is in an even better position to get you where you 're going . ' Spirit has long taken a tongue-in-cheek approach to its promotions , calling itself the 'home of the bare fare ' The company has already used the provocative slogan , 'Home of the Bare Fare , ' when discussing their competitive pricing in the past . In fact , the phrase is currently emblazoned on several of its aircraft . In much the same vein , Spirit spokesman Paul Berry said , in a statement , that the latest campaign was simply a reflection of the airline 's unconventional and quirky personality . 'Spirit is n't your typical airline and we do n't want to be . 'We enjoy being different than other airlines . ' Spokesman , Paul Berry , has said that the latest campaign is simply a reflection of Spirit 's quirky personality . However , some customers have took to social media to question if the ad campaign has gone a bit too far . 'When it comes to advertising , different means we do n't spend a lot of money on advertising -- because that just increases fares . 'But we 're also different because our ads are fun , provocative , sometimes silly and often irreverent . 'They get lots of attention . 'The vast majority of our customers find these types of ads humorous and accept them for what they are . We understand there is a small group of people who feel differently . '
