check-in agent

[hpnx6110]

Hi,
I have got a question connected with customer service at London Heathrow Airport.
There is one handling service for all airlines in Poland. When I was trying to find who checkinging-in passangers at Hethrow I didn't find name of a company.
Is that mean every airline is responsible for checkining-in their passangers?
What if I would like to be an check-in agent at Heathrow ... where should I look for job opportunities?
Have a nice day :)
I'm sorry If there is some similar question on the forum, but my English is not good enouqh to find these posts.

Im not sure of all the handling agents in LHR but I know Aviance are quite big they look after BD and SQ for sure, BA look after themselves and Menzies have a big presence aswell, I know they look after EI at least, I believe KLM, SAS and AC all provide some forms of ground handling and I believe Servisiair are also present, perhaps someone else could give you more details.

Thank you so much.
I also found something like SWISSPORT.

Swissport - although 1 of the world's largest handling agents - do not currently offer check-in services at Heathrow.
