Hi I need to get to Luton Airport next week from central london and have looked up the train times and fares so I can leave st pancreas st at 5 and it will get me there. But the cost is 22.50 so for 3 adults it will cost us 67 pounds apart from taking a bus which will leave us with less time in London is there any other way. Would a taxi cost the same and I persume take longer as it is the 5pm time ? any ideas on how I can get a cheaper tain tickets?
