Aeroplanner / Jeppesen
You pay your money and make your choice of course.
I too use it for short flying trips, particularly in order to be able to prepare in advance of arrival and find the 1 month subscription facility and national coverage convenient to be relatively cheap.
I would like to do the comparison with jeppesen sometime as well.
Above all a similar facility in the UK would be great but then there is notthe market for it I guess.
I saw that the Jeppsen has worldwide data - does that include the UK and at the same level of service ?
