airline and flight number
"In range" on flight status means that the aircraft is within the designated distance from its destination airport and is expected to land soon.
"Flight departed" means that the airplane has taken off and left the airport to begin its journey to the destination.
"Seat at gate" refers to having a designated seat at the boarding gate where you wait to board your flight. To ensure you have a seat at the gate for your upcoming flight, make sure to check in early, either online or at the airport, and arrive at the gate well before the boarding time. This will increase your chances of getting a seat at the gate and having a smooth boarding process.
GMT stands for Greenwich Mean Time, thus in airline industry every flight is reported after the GMT Time or World Time. That's just my opinion :).
