BUZZ-Airport and Aviation Services: strong volume growth continues - Barclays
** Barclays (LSE: BARC.L - news) says 2018 will be another year of strong volume growth for airport and aviation services thanks to continued airline capacity growth and robust European and U.S. markets
** Broker's top picks: AENA (Dusseldorf: 26876733.DU - news) and BBA Aviation (LSE: BBA.L - news) , due to their strong profit and cash conversion of volume growth and opportunities for capital allocation
** Barclays cuts Enav (Milan: ENAV.MI - news) to "equalweight" despite having the same qualities due to lower valuation upside
** Broker reiterates "underweight" on Aeroports de Paris and Fraport (IOB: 0O1R.IL - news) as their profit growth in 2018 will be largely driven by acquisition consolidation
** Fraport in particular is struggling to convert passenger growth into profit one and has a rising capex burden on its shoulders, according to Barclays
