For me personally, I'm hispanic, so I can definitely relate to many things you are talking about in here, which is awesome, but the thing I see that really sticks out your voice and how you describe the things you see. You start with your steps out of the plane then your experience inside the airport, to meeting your tia and tio, then driving over to your grandma's house and finally arriving there. I like the flow of the story. And everything you do in the present time, you directly relate it to experiences you've had in the past. Showcasing great moments of dual existence. The way you describe the things you see and how it was in the past, all while allowing the events in the story to play out one after the other, is a great aspect of this piece. Good job!
Because I really enjoyed the experiences you've had both in the past and present in your time in Mexico and hearing about that, I encourage you to carve more of that and translate it into the story. Some things that I thought that were cool and suggest you can expand on, is the smell of familiarness. What did it smell like? Perhaps you can make a metaphor or a simile or some form of descriptive language. Also I think it would be fun to visually describe your tio y tia. Maybe noting similarities or differences in their physical features from now and before. Describing la cochera would also be pretty interesting. Visually placing that familiar image into the reader's head to show them what you were seeing. Also may be describing the weather as with the smell would be fun to expand on. So what did it feel like to step back in time in terms of weather.
I really liked this piece, even though it's just a draft. It's filled with a concrete storyline that describes you experiencing the present while recounting the past. With the descriptive detail you use to recount these memories and the tone of your writing, it made me interested to learn more and experience what it was like for you on this journey through the past. It would be fun to expand this story through various details, but that's up to you. Good job, hope to see more!
