Reading from left to right:
2 is the segment number on your itinerary. Segment 1 is used as a header.
EK 641 is the flight prefix and number. This is Emirates flight 641.
L is the booking class for this sector. L is often a midprice economy booking class.
29NOV is the departure date, in the time zone of the departure airport.
2: The numbers after the date are days of the week. 1 is Monday, 2 is Tuesday, etc.
KBLDXB is the origin and departure airport codes concatenated. This is a flight from Kabul to Dubai.
HK1 is the flight status. HK means your reservation is confirmed. 1 means it is confirmed for one passenger.
I: The letter or number before the time is the departing terminal, in this case the International terminal at Kabul. On the next flight it is terminal M from Kuala Lumpur.
1630 the departure time at Kabul, local time.
1905 the arrival time at Dubai, local (Dubai) time. Sometimes you will see a +1 to indicate that the local time is one day ahead of the date at the time and place of departure.
*1A/E* is a tag indicating that the sector is eligible to be printed on an eticket instead of a paper ticket.
Seems pretty unprofessional.
