IATA Resolution Resolution 830d

My travel agency sent an email noting that they cannot book multiple flights for the same person on different airlines. That there may be a charge if this happens. Just heads up for people booking 'safety flights' where both flights are in the air at the same time.

Not sure how you can avoid this, but for example, maybe if you book directly with an airline and not a platform like expedia, it shouldnt impact. How would they know?
