Bulk Upload

1. Prepare a CSV with two columns: name and iata_code (header row optional). Download a sample.
2. Optionally add logos: name each image after the IATA code (6E.png, AI.jpg) and attach them as images or one ZIP.
3. Upload. Rows with problems are skipped and listed so you can fix and retry.

Tip: you can upload logos alone (no CSV) to add or replace logos for airlines already in your list.
