Recently booked an international trip with two other persons. Since the others are MP members but have no status, I offered to book the flight so that they could get E+ seating. When making the reservations, I gave my info as passenger one, and the others as two and three respectively. However, in all cases passenger 3 has received all related email confirmations (e-ticket, receipt, and upgrade confirmation) but I have not received any emails. I never provided passenger there's email, so system must be using the email on MP profile. I called 1k desk to make sure my email was on itinerary, and agent confirmed all was normal. But now en-route I do not receive any messages or any text messages about flight status. Any ideas what might have happened? Should I have done something different when booking?
