If by pension you mean a defined benefit or final salary type scheme, virtually no-one offers those for new joiners any more and with good reason.
Guaranteeing a particular return on investment to someone 35 or 40 years in the future is fraught with peril, note the likes of BA and their one BILLION pound short-fall in their pension scheme, or the US Auto industry who spend more paying their retired workers than they do their current staff!
As you've come onto the Mid-east forum I can tell you that EK have a Provident fund where they contribute a percentage of your salary to an investment fund. On leaving (after a qualifying period) you get its' current value (similar to 401K in the US).If you worked here a LONG time (and I mean 25 years or so) it MIGHT form a reasonable part of your retirement, but probably would still not be enough to ensure a good lifestyle after your working life is finished.
In this day and age, your retirement is your problem and you would be wise to start planning for it now.
