Hello and welcome to SAYNOTO0870.COM.
As sherbert says, please post some basic information as a starting point. It's not so much a case of "does anyone have a number" as "can we find a number"? It's like playing detective.
In this case, however, I believe that you're referring to the company whose website is
wwwaegeanair.comIts
reservations page gives 0871 200 0040 for UK callers and
(+30) 210 6261000 for USA and other countries.
The
headquarters address is given as:
Aegean Airlines Headquarters
31, Viltanioti Str.
145 64, Kifisia, Athens, Greece
Tel.: +30 210 62 61 700, Fax: +30 210 62 61 900
So it's based in Greece and the number highlighted above is a geographic one in Athens. It's often useful to know how the 08 number answers, so you know what you're looking for. I called the 0871 number and it went through to the same recording as is on +30 210 6261000, so it looks like this is the alternative..
I've added an entry for this. Probably best to use a call provider such as 18185, so as to make it worth your while avoiding the 0871 number as international calls are quite expensive with line providers like BT and Virgin Media.
