Feature request..
Add in somewhere a place to add one E-ticket # or reservation number for all segments per passenger.
Better yet, Maybe even make a second screen where you can add all the e-ticket info at once (with separate tabs per passenger, and one master tab for all passengers) instead of scrolling through each flight segment and adding the data individuallly.
It would have to be cohesive (so it would need to pull the flight number or route info) so you know what's what.
I wouldn't necisarily remove the current entry method (since people are used to it) but it should be a useful addition / alternative.
This request stems from me having just created a 3 passenger, 8 segment itinerary with the same e-ticket number per passenger for all flight segments. There were multiple partner booking reference numbers for different flights, but they were the same for each passenger on the booking.
