Need to select 2 letters with RegExp

Question

The thing is I have a string like this:

iata_code@name@city@gmt_offset@country_id@iso_code@latitude@longitude@air_os@air_lx@air_lh@air_sn@air_nz@air_su@air_s7@air_a3

The marked symbols are need to be selected with regexp. It would be great if someone smart will be so kind to help me :)

I was able to write only:

/(@air_)\w+/g

Thanks in advance!

Answer 1

This lookbehind regex should work:

(?<=air_).{2}
