Wake up call means that out of homebase (LUX) you get a call one hour before check in. The reason is that although you have a schedule the flight might be delayed, so in order to give the crews a chance for maximum rest, you get the call. (Works fine if you live within 30min. of LUX, otherwise people have to work out their own wake up).
Downroad you get a wake up call one hour before pick up in the hotel, same reason as above!
Trips run between 2 days to 16 days. Average 7-8 days. People's preference varies, commuters like long trips in order to not be at homebase for few off days, but not as a rule. Some long trips touch nice destinations while shorty's might be boring, anyway, looking into the bidding system is always a thrill seeing all the destinations and picking your preferred ones then.
One thing though: You might be gone for some time down the road, so if you need to see your family every other day, stay away from the job, you won't like it! Otherwise best job that is around (Imho)
