Decoding_Flight_code

Problem_Decoding Flight Number:

2 - Write a script which processes incoming data about airline flights. The script should expect to recieve a flight_code as a string. This string is a coded version of information about that flight. The schema below shows the format:

```

AA0123.DFWHNL.I0150

```

Example | Name | Possible values

------ | ---- | -------

AA | Airline | AA = American Airlines
JB = Jet Blue
SI = Singapore Airlines

0123 | Flight Number | 0000 - 9999 (zero padded)

DFWHNL | Origin and Destination | Any combination of 3 letter origin and destination IATA airport code.

I | Status | I = Infight (ENROUTE), G = Ground (departing)

0150 | Time | Can be any integer representing a number of hours and minutes. This will be the time to departure or ETA if enroute.

Other Notes about the format:

- All letters in flight code can appear in upper case or lower case.

- If the two periods (.) are not present the flight code is invalid.

- Flights departing in less than 30 minutes should including the NOW BOARDING message (see below)

The script should print the information in a human readable format. Your script should prompt the user to enter a flight code, print the result ads shown below:
