Lost black wallet in DUB airport on the 28th of July

TL;DR: Lost wallet on 28/07/2016 (flight EI 609 from AMS to DUB) either in airplane or on airport. Contains Dutch ID-card (initials N.W., first name Nick), bank card (with hardly any money in it), Dutch public transport card ('OV-chipkaart'), Dutch workers organisation card (from the 'FNV'), cash, Dutch health insurance card (from 'Menzis'), Irish windsurfing card from Avon Rí, my boarding pass and possibly more. Aer Lingus doesn't seem to have it. Last week Thursday, the 28th of July, I flew with Aer Lingus from Amsterdam to Dublin (flight EI 609). Unfortunately, once I got to the passport-checking desk (before the baggage collection hall), I realised I didn't have my wallet. The customs staff allowed me to go to an Aer Lingus customer service desk, and checked if my wallet was still on the plane (letting me collect my baggage in the mean time). After around three quarters of an hour they finally told me that they couldn't find my wallet, but that there was a chance that they'd find it later and that I should call back the day after. Well, a week later it still hasn't been found by Aer Lingus, so it seems like my wallet wasn't lost on the airplane (or someone must've taken it from there, if I did lose it on there). It might be at the airport itself, don't think I've checked there yet. I also still have to report it to the police. If you've found it, please make sure it's returned to me. My address while I'm in Ireland is somewhere near Blackrock / Mount Merrion.
