Does the bus service from Los Cristianos to the south airport run at night?

I got the bus several times at night from Las Americas (same,one that goes to Los Cristianos) and it always arrived.... Not in time,but it did eventually.... I agree that you don't really need to reserve a taxi... Just wait for the bust until the last min... If it doesn't show than get in to a taxi.... They are always there....

Thanks to you all for your responses. We will aim for catching 4.00 am bus as I think the taxi fare is about 25 euros??

Yes Wendy we were €25 a few weeks ago and that was a day flight,might be more during night
