Because I am so busy, I don't have time to 'phone round 20 hotels to get a room, or mess about with airline schedules because a flight is full...
That's why I listen, learn and share here. I know that a BA Gold card guarantees a seat. The right card at Marriott guarantees a room etc. etc.
Next time you are stuck at an airport for 3 hours waiting for a conection because the direct flight was fully-booked, you may consider 10 minutes a day learning from this site worthwhile?
MERRY FLYER
