Tips to Book a Cheap Flight Ticket to Houston from London

Cheapfaremart endeavors to help you with the airfare comparison so that you can find a low-cost flight to Houston from London. However, attention to some flight booking hacks may make a huge difference to your savings. Here they are.
1. The cheapest time to fly from London to Houston
On a long-haul flight route, opting for a late-night or early morning flight, you may save more. Such a flight receives less attention as families with kids avoid traveling with them because of the sleep challenges involved. If you don’t mind taking some trouble, go with a red eye flight to Houston.
2. The cheapest day to fly to Houston from London
Travelers postpone their holiday to weekends, which leads to an increased demand for airline tickets on a Friday, Saturday or Sunday. It’s better to avoid clashing your travel dates with them by flying on a Tuesday, Wednesday or Thursday. You are most likely to come across some great flight deals on these days.
3. The cheapest season to fly from London to Houston
Summer (May to September) is the cheapest season to visit Houston, TX. Summers are characterized by high temperature and humidity. The upper limits reach mid-90s °F. Humidity is never going to spare you, irrespective of the months you choose to visit. It maintains its consistency (above 70%) throughout the year. Adjust your travel dates in March and April to avoid blistering summers. Winter (December to February) are also favorable for tourism.
4. The cheapest airlines to fly to Houston from London
As of now, no low-cost airlines operate on this route. However, that doesn’t take away your right to book cheap flights to Houston. Airlines start accepting flight reservation as early as 331 days before the scheduled flight departure. It’s always good to confirm your flight ticket well in advance. Rather than waiting for some unexpected low price, it’s good to bag a flight that sounds average or reasonable.
