The translation to Spanish using Present Progrssive Tense is:
<u><em>Estoy yendo</em></u><em> al mostrador de boletos a las seis y </em><u><em>estoy caminando </em></u><em>por la seguridad a las seis y media. Luego me </em><u><em>estoy dirigiendo</em></u><em> a mi puerta para abordar a las siete.</em>
Explanation:
The translation of the paragraph is:
<u>I'm going</u> to the ticket counter at six and <u>I'm walking</u> for security at half past six. Then <u>I'm heading</u> to my door to board at seven.
Remember that the progressive present mentions actions that are being carried out at that time, so converting a paragraph with specific hours loses some sense, however, I want to tell you additionally that a practical way to identify the progressive tense in Spanish is that the main verbs have <em>"ando"</em> or <em>"endo"</em> endings, in addition to some form of the verb <em>"estar,"</em> as the personal pronoun used in the sentence precedes them, <em>"yo,"</em> the only conjugate form that was required is <u><em>"estoy."</em></u>
