Nah, nothing to my knowledge that regularly works from the airport itself. It simply isn't like the London hubs which are big enough, busy enough and far enough out from the city - but also close enough to several other urban and residential areas without hotels themselves - to bring enough punters for girls to base themselves there. While I have clocked the very odd one in the past, Glasgow Airport - getting older and shiter with less routes by the week - is simply too small and too near both Paisley (which dreams to think of itself as a reasonable-sized town in its own right) and the city centre, being only a 20 min drive, for any girls to consider it as even a second or third choice. Even Edinburgh, which now continues to consistently out-perform Glasgow in terms of routes and passenger numbers - but without the additional deterring factor of an second wannabe-city right beside it - is in the same non-punting position, for much the same reasons.
Gabriella (

External Link/Members Only) - not to be confused - are your two closest, reliable options as the crow flies, in terms of where you're going to be in Govan. I haven't seen either myself but both are well-reviewed, consistent performers as you can tell from the links below. Gab seems to be more vanilla but still enthusiastic, and also more flexible in her availability - with her phone number usually up. Ella, on the hand, offers the sub-stuff you might be looking for, but needs to be contacted through AW despite claiming to be speedy in her correspondence in this regard.
Without deliberately being pedantic however, trying to limit which girls might suit your needs in terms of proximity and availability hasn't really been made any easier, despite the additional details you've added about your trip. I appreciate you might very well not know the exact timing of things till the day itself, but were you planning to - or would you at least consider - making your punt a stop-off en-route to or from the airport, for example? As even if, for instance, you only have two hours max. to play with on your way out - between leaving Pacific Quay and needing to check-in - that would still be more than enough time to get a taxi anywhere in the city-centre (10-15 min), for an hour's punt, and back out to the airport again (20 min max). If that's the case, you probably have most of the girls in Glasgow to choose from, including several well-rated regular tourers working mid-week from city-centre hotels, depending which specific day you're here.
