ALR meaning in Airport Code ?

Alexandra (Greek: Ἀλεξάνδρα) is the feminine form of the given name Alexander (Greek: Ἀλέξανδρος, Aléxandros). Etymologically, the name is a compound of the Greek verb ἀλέξειν (alexein; meaning 'to defend') and ἀνήρ (anēr; GEN ἀνδρός, andros; meaning 'man'). Thus it may be roughly translated as "defender of man" or "protector of man". The name Alexandra was one of the epithets given to the Greek goddess Hera and as such is usually taken to mean "one who comes to save warriors". The earliest attested form of the name is the Mycenaean Greek 𐀀𐀩𐀏𐀭𐀅𐀨 (a-re-ka-sa-da-ra or /aleksandra/), written in the Linear B syllabic script.
