Here are the offers for new loyalty program members
This continually updated article reports all the welcome bonuses available to new loyalty program members

Airlines, hotel chains, and all businesses in general that have a point collection system are constantly looking for new members. The more cards there are around, the higher the value of the loyalty program will be, the more data possessed the greater the revenue from promotional activities.
In this article:
If the store down the street gives 10% off to new members and the supermarket offers €5 on the first shopping trip, when it comes to travel the welcome gift is paid in points.
I will try to keep this article updated at all times, including new submissions and deleting expired ones.
ITA Airways
Usually the Italian company (almost) always has a welcome bonus, but not at this time. The last offer expired on Christmas Eve and included a bonus of 1,000 Volare points. As a reminder, currently the points can only be traded with a counter value of 1000 points=5 euros.
Etihad
Did you get your flight cancelled, miss your connection, land late?
You could get up to 600€ compensation per person
The national airline of the United Arab Emirates has a small bonus of 500 guest miles for all new members, there is no expiration date to this offer, and it is also not super generous so consider carefully whether it makes sense to sign up or wait for something more generous.
Qatar Airways
The carrier known around the world for its QSuite often launches promotions to attract new members, right now there is an active promotion that generates a bonus for new Privilege Club members upon completion of the first flight.
To get the bonus it is necessary to register by December 31, 2024 using the code JOINPC24 And travel by June 30, 2025. You will accumulate 2,000 Avios in Economy Class and 4,000 Avios in Business or First Class.
