Are Boeing 737-800s grounded?
The 737-800 is not grounded (and never has been). The aircraft type has an excellent safety record. Since 1997 over 5000 have been produced. 

The 737 MAX 8 is its successor. The aircraft is very similar to the 737-800. One of the differences is the placement (more forward and higher) of the slightly bigger engines. This changed the stability of the aircraft under certain flight conditions, causing Boeing to introduce the Maneuvering Characteristics Augmentation System (MCAS). The MCAS played a crucial role in two recent crashes of the 737&nbsp;MAX&nbsp;8, leading to the grounding of the aircraft type. 

The 737-800 does not have such a system and is therefore not affected.



Airlines typically use IATA aircraft codes (3 letters) or ICAO aircraft type designators (4 letters) to indicate the aircraft type used on the flights.

For the Boeing 737-800 the ICAO type designator is B738, while the IATA codes are 738 and 73H.

The Boeing 737 MAX 8 has the ICAO type designator B38M and IATA code 7M8.
