If you travel regularly, it makes sense to join the loyalty programs of the airline with which the majority of your flights take place. Most major carriers are part of one of the three airline alliances – Oneworld, Skyteam or Star Alliance.
There is no best alliance, but one of them will almost certainly suit you more than another because of your location and the destinations you regularly visit, or the airlines you regularly use. Bear in mind that there are also associated financial products for alliances, meaning you can accrue additional benefits using a credit card allied with one of them.
As you rise through the tiers of your airline program, you will also be progressing through the tiers of that alliance, giving you benefits across member airlines including earning and burning miles and lounge access. Here’s a guide to the benefits available.STAR ALLIANCE
