Mary Brown is expecting a baby in about three months.
She and her husband decide to travel to their home country across the ocean in five months (when the fares will be at their lowest) with the newborn, to visit his/her/its grandparents.

If they book today, the best-fare tickets have to be issued within three days of booking.

This is International Travel.
The Airline needs full names (as per passports), dates of birth and passport numbers.
How will the Airline be able to issue the tickets within three days of booking,
if the exact date of birth (in about three months) is not known?
The parents might tell the Airline what they intend to name the newborn (if they already know the gender and have decided on a name.)
If the parents did not try to find out the baby's gender, will the Airline accept:
"If it's a boy he will be Thomas, if it's a girl she will be Tomasina."?

Cheers
