income varies day to day. some days are better than others.
but, as a safety guide, u can estimate around RM15-20 per hour average
that is after comms deduction but before maintenance & fuel.

it really depends on the type of car ur getting, how much is your installment monthly, how much fuel you consume, how much is the maintenance.

from my estimate, from 100% fare
-25% comms
-10% fuel
-15% maintenance (service/tire change/battery/road tax/insurance)

nett income is around 50% of fare.

if u drive 8hrs a day, u can safely assume at least 200km of travel per day.

welll...at least ur car is paid for, maintenance taken care of...

of course, its actually hard work. not easy money. read thru the other threads and u'll see so many complaints by drivers.
and u need to work thru ur installment period...which is easier said than done.

btw, i'd actually advise u to choose a car from the gc+ list instead of gc...with a gc+ car, u can turn on both services and accept both request. gc+ returns slightly higher fare compared to gc....
not sure if persona is gc or gc+

but of course its entirely upto u

gc min fare RM5
gc+ min fare RM8

gc to KLIA RM65
gc+ to KLIA RM75

like i said, its slightly higher fare only compared to gc but if u know how many RM5 trips there are, u'd be grateful ur collecting RM8 instead, doing same thing.

since ur getting a car anyways, why not get something more comfy? u feel better, rider also feel good

yes, if u turn on both service, then means ur open to rcvd either gc/gc+ whichever comes first.
normal driving, i only turn on gc+
in KLIA, i will turn on both just to check the queue.
from what i notice, gc queue 700-800 is about the same wait time as gc+ queue 200-250 which is between 1.5 to 2hrs

so if i see gc+ queue not too high, i will switch to gc+ only. same waiting time, might as well get RM10 extra right?

give u benefit of doubt.

yes, its quite normal to wait 1.5 to 2hrs at KLIA for a ride. reason is, KLIA is based on queue, first come first served (well, some play by different rule, but that's a different story). So seeing you're not the only or earliest driver to be at the queue, its normal to get 700-800 queue number.
quickest camp time at KLIA for me is around 1hr which is in middle of the night.

in KL is different story lo...so many riders, short trips, long trips, ppl going lunch, going appt, going hospital, going shopping, back to office, back to home etc etc...of course won't have to wait so long for a ride.
if in KL city, u can expect B2B non-stop, especially during peak hours or a 1-2 min break in between during non-peak hours. at most 5 mins break in between rides. if more than 10mins without a request, something wrong already.

ok...first, imagine u accepted a request to send rider from KL city to KLIA. trip is 50km, RM65.
after drop off, what u want to do? go back to KLIA empty car? its a 50km return trip.

or, u can hv 2 other choice:

1) drive to putrajaya or nearest city and start driving there
2) wait for ride back to KL city/some where
3rd choice is DON'T accept any KLIA rides from the city. that way u'll be driving in city only. dun forget, in city, u might caught in jam. trip to KLIA usually smooth traffic.

as mentioned, return trip from KLIA is RM65. 2 trips, consumed 4 hours (1 hr to, 2 hr wait, 1 hr return) is RM130 which gross about RM30/hr. If u get an even further return trip, like to genting, even better!
if u lucky, ur able to make same fare in putrajaya/cyberjaya but u'll be driving non-stop.
in KLIA, ur idle, no petrol used, u relax and play fb/tumblr

also discussed in this thread, many agree upto 2hrs wait is reasonable (given 4hrs total)...more than that then its probably not worth it.

if u so worried kena ban, then u need to behave better lor...install dvr in car to record the riders. if some idiot report u for no reason at least u can defend.
if u behave or wanna behave like gangster abang taxi, then god bless, better u dun buy car and drive.
some riders are idiots..u'll see many like those and cant avoid. just do ur job, and things should be ok. u'll need to be damn 9 suei to kena ban for no reason.
