Some of the chemicals that give foods their distinctive aroma are passed in the urine. A number of foods can cause your urine to have a strong odor, especially if you aren't drinking much water. Common culprits include garlic, onions, asparagus, and coffee. Large amounts of fish, meat and eggs in your diet might also cause a change in urine odor.
Contact Delta for Assistance. It is important that the UMNR is identified in the PNR prior to departure. If a passengerâs Secure Flight Passenger Data (SFPD) indicates, by the date of birth, that the traveler is a minor, and the minor is traveling alone, Delta requires additional UMNR information be entered in the PNR.
Unfortunately, Delta requires you to purchase very high fare classes (Y, B or M) in order to upgrade any international flight. For flights within or between the US and Canada, you have a few more fare classes to choose from: S, H, Q or K (in addition to Y, B and M). This still leaves out the lowest economy fares.
